Rio Ferdinand was 24 when we signed him - the same age as Blind and Rojo are now - and he was the world's most expensive defender at the time. We had serious defensive problems in 2001/02 and threw money at it in the summer.
Rooney, at 18, was the world's most expensive teenager of all time. Two other Manchester United signings have made the top ten since: Anderson in 2007 and Luke Shaw in 2014. Paying big money for a highly regarded British (or Irish) youngster is certainly nothing new. We broke the British transfer record for Roy Keane in 1993.
Vidic and Evra were 25 when we signed them. One year younger than Di María, same age as Ander Herrera, older than Blind or Rojo. They weren't gambles in terms of the price but we couldn't be sure that they would cut it at this level. Much like Blind and Rojo, though with inflation and desperation, they are obviously more expensive.
Even Ronaldo came for a relatively huge fee. In 2003, 12.25m was big money for an 18-year-old, even if we blew it out of the water a year later with the Rooney transfer.
It is true that we didn't sign all these players in ONE transfer window. But then again we didn't finish seventh in any of the previous seasons. Now here we are, after years of poor performance in the transfer market and after a horribly botched managerial appointment - we needed to do in one window what we usually do over several years. But we did what we always do: sign highly rated youngsters, plug some gaps with relatively inexpensive 24-25 year olds and making one or two really big signings.
Yes, Welbeck's gone. It doesn't represent a change in identity though. It merely shows that he didn't want to be a squad player and the management felt he didn't have enough in him to be first choice. Considering that after a season of playing Welbeck as one of the main strikers, Fergie went out and got both Kagawa and Van Persie in, it's not a great surprise.
