The most pertinent football truism for Manchester United this summer is that you should always build when in a position of strength. Interestingly you should also change things from a position of weakness or mediocrity, so really change is the underlying message but we'll skip that.
But Sir Alex Ferguson has already flagged up the difficulties of recruiting. The best players are almost all at the best clubs - and they simply don't like selling to each other. With that in mind he is talking about only one summer signing:
"Managers are back at clubs, back at training and you can get some dialogue now if you are interested in somebody but I wouldn't think [we will sign] any more than one player."
But this is hardly an anomaly, Ferguson has in recent years brought in just one major player each summer plus sometimes a couple for the future. Last season was odd in Hargreaves being the major signing - but the sudden availability of Nani, Anderson and Tevez (albeit on loan) was deemed to be too big an opportunity to miss. These purchases were mostly offset by selling Heinze, Smith, Rossi, Richardson, Shawcross and Bardsley for about £30m. Leaving a deficit of around £20m for the season.
In the summer of 2006 Carrick was the big signing, in 2005 there was no major signing as Park and van der Sar arrived in moves funded by selling Phil Neville and Kleberson; 2004 saw Rooney arrive, 2003 Ronaldo and 2002 Ferdinand. Ferguson has some history of adding just one major player in the summer.
The recruit will surely be a forward, unless Ronaldo does leave in which case there will be a requirement for a goal scoring wide player as well like Messi or Sneider; but whilst Ronaldo's future is in doubt there is little onus on United to sell.
In goal a season of transition should see van der Sar's successor emerge from the battle between Kuszczak and Foster; barring injuries the reserves will be sent out on loan or permanently.
Defensively Gerard Pique (£5m) has been sold on and could be joined at the exit door by Jonny Evans (£3m) and Mikael Silvestre (£1m) and although Gary Neville should be available there could yet be recruitment in this area. But Brown, Simpson and O'Shea do offer enough depth.
Midfield is strong and Anderson will be expected to keep progressing at Paul Scholes expense; Carrick will vie with Fletcher and Hargreaves to sit alongside - although the Champions League final pointed to the potential for Carrick and Hargreaves to play together with a flamboyant third player.
What United have missed in recent years is a striker - they have plenty of forwards but a big target man should always be an option, even if not always the first choice. Louis Saha has proved to be constructed of balsa wood and needs replacing. Although Manucho (who looked good at the Africa Cup of Nations) and Campbell (who impressed at Hull) will be available a big money forward seems likely to arrive.
I guess that the reality is that change is always needed at football clubs, but building on a strong position is always easier than changing a failing structure - and in that respect United can target just about any striker in world football (with the usual exception of Liverpool's forwards even if Fernando Torres would be a stunning addition). Dimitar Berbatov (£23m) will remind all United fans of a certain age of a certain Frenchman born in a certain 'good year for English football' - and would add the arrogance and touch that can elevate the United attack to new heights.
