Legacies can be tough to live up to, as evidenced by the recent history of the Manchester United number 7 shirt. Since the departure of Cristiano Ronaldo for Real Madrid in 2009, the sacred digit has appeared on the backs of Michael Owen, Antonio Valencia, Ángel Di María, Memphis Depay, Alexis Sánchez and now Edinson Cavani, with few truly memorable moments.

There have been times this season when United have looked like title challengers and Cavani has played his part, to be fair. With Manchester City again in an all-conquering mood, United aren’t going to win the Premier League this season and success is more likely in the Europa League. If Cavani is to depart at the end of the campaign, it would be a perfect way to sign off and it’s certainly possible – a visit to the STSbet site sees them favourites at 7/5 to win the Europa League.

If and when the Uruguayan goes, great things will be expected of the next number 7, but it should be noted that this legacy has more than a little legend retrospectively attached to it. Consider the case of George Best, who is considered to be the originator of the noble lineage.

According to the English National Football Archive, the Belfast native played 474 times for United, each time as a starts. Once, in March 1969, he donned the number 9 shirt. He wore number 10 on 39 occasions and had 8 on his back 42 times. In a total of 140 games, including the 1968 European Cup final win against Benfica, he was number 7. However, in 252 of his games – more than half – Best wore number 11. In his final six seasons with the club, he appeared as number 7 on only 32 occasions. We stand to be corrected, but we remember that, when Ryan Giggs emerged, one of the reasons he was called ‘the new Best’ was because he wore 11 too (but not always).

The 1968 win, and Best’s performance, tends to elevate his association with number 7. In a feature on numbers in FourFourTwo in 2012, the editor of the fanzine United We Stand, Andy Mitten, gave his thoughts on the shirt:

The 7 wasn’t a big thing at United until Cantona. After all, Ralph Milne wore 7. Cantona was when the press started to make a big deal about the significance. United were happy for them to do that because it added to the legend, it was something else to market.

Generally, Best had worn 7 when deployed on the right wing. One of his successors there was Steve Coppell, who joined United in 1975 and won 42 England caps, but he generally isn’t included in the ‘star’ bracket. Coppell wore 7 until 1981, and wore it against Tottenham in the League Cup early in 1981-82, when Bryan Robson, newly signed from West Bromwich Albion, wore 11. Coppell missed the next match, against Manchester City in the league, and Robson first wore the shirt with which he would become linked. Not because of any notion that he was carrying on Best’s mantle, though. He wrote in his autobiography, Robbo:

At West Brom, especially during Johnny Giles’ management, I played in several positions and had a variety of numbers on my back. That didn’t particularly bother me because I just wanted to play as often as possible. Then it occurred to me that my better performances came when I wore the no. 7  shirt and I came to regard it as my lucky number.

So, when I joined United, I asked if anybody minded my having the number. Steve Coppell, who usually took that number, wasn’t in the starting line-up against City and said he didn’t have a problem with my wish, anyway. None of the lads objected either so the no. 7 shirt was mine.

In the late 1980s and early 90s, with Robson often unlucky with injury, the number was donned by a motley crew including Peter Davenport, Russell Beardsmore, Clayton Blackmore, Neil Webb and Andrei Kanchelskis. When fit, however, the captain would always wear it. The signing of Eric Cantona in November 1992 changed things. Cantona’s first match was in a friendly against Benfica, when he wore 10, and then his league debut was as a sub against Manchester City in early December.

When he made his first start, it was as a direct replacement for Robson, with number 9 Brian McClair dropping back into midfield. With Cantona playing a key role, United powered up the table, eventually winning the title. Robson’s only other start that season would be in the final game against Wimbledon, when Cantona wore 11. Squad number were introduced for the 1993-94 season, though, and it was Cantona who was assigned 7 with Robson now 12. In his book, Robson revealed that it wasn’t a problem, seemingly ignoring the ‘luck’ reasoning:

I didn’t even mind losing the no. 7 shirt to Eric. I knew I would be used a lot as a sub in the 1993-94 season and Eric had already shown his value to the club. We’d won the league in his first season with us and it was obvious he was going to be an important player for quite some time. He’d always liked to wear the no. 7 so, that summer, when the boss was working out his squad numbers for the new season, I told him I didn’t mind having a different number. I’d had a great World Cup in 1982 wearing 16, so it wasn’t a problem having 12, 14 or any other number. I was, after all, now a bit-part player for United.

Incidentally, Robson did play in all four of United’s Champions League games in 1993-94. Teams lined out in 1-11 in Europe until the end of 1995-96 and in those games, two against Kispest Honved and two against Galatasaray, Cantona wore 9 to accommodate the captain, who left at the end of that season to take over as player-manager of Middlesbrough.

Cantona would retain 7 until his retirement after the 1996-97 season, in which David Beckham had worn 10. As we recall it, Teddy Sheringham arrived from Tottenham and sought to wear 10, which resulted in Beckham reluctantly taking 7, but this article takes the view that he always wanted it, while a passage in Roy Keane’s new book also promotes that view. If Beckham did love 7, he didn’t fight hard to wear it. For the 1992 FA Youth Cup final, he wore 6 and in the following year’s decider he had 8 on his back. In 1995-96, United wore 1-11 in games in both the Coca-Cola Cup and FA Cup and Beckham wore both 8 and 10.

Beckham’s 2003 autobiography My Side tells of how he learned he was to become number 7:

When I first got into United’s first team as a regular, my squad number was 24 [he had worn 28 before that, too]. The following season I was given the number 10 shirt. That meant a great deal to me: Denis Law and Mark Hughes had both worn it before me. Maybe the history that went with the number was why I scored so many goals wearing it. I remember, though, the summer we signed Teddy Sheringham, the boss actually took the trouble to phone me when I was away on holiday in Malta to tell me he was taking that squad number off me. No explanation, no alternative and no argument. I remember saying to Gary Neville at the time:

What’s he done that for? Why would he phone to tell me that? Did he just want to make sure he ruined my holiday?’

I was devastated, trying to work out what I’d done wrong. Then, a month later when we turned up for pre-season training, he had a new shirt ready: the number 7. The boss handed me Eric Cantona’s squad number. The surprise of that honour stopped me in my tracks.

Elsewhere in that book, Beckham tells of how Robson was his idol but clearly, despite having 10 taken off him and 7 being free with Cantona leaving, it never occurred to him to ask if he could inherit it.  From Beckham’s departure in 2003 until the present day, things are fairly straightforward. Cristiano Ronaldo wanted to wear the number 28 he had had at Sporting Lisbon but Alex Ferguson told him he had to wear 7 and ultimately, he continued the narrative. His successor was Michael Owen, who definitely did not. After Owen left, Antonio Valencia switched from 25 to 7 but switched back just as quickly and the shirt was unworn in 2013-14.

Ángel Di María would appear to be a worthy successor to the tradition, but he didn’t work out and nor did Memphis Depay. Alexis Sánchez had his moments, but was yet another who couldn’t live up to the mantle. That Cavani took 7 was probably more down to the lack of low-number options as much as any hopes of him reigniting the aura of the number 7, but a successful end to the season for him and United could see him remembered fondly, albeit not at the levels of Best, Robson, Cantona, Beckham and Ronaldo.
