To me, I guess the talking points would be Ferguson's decisions and tactics which totally failed against Barca:
1) Rio Ferdinand hasn't played for 3 weeks, and suddenly he was allowed to play. I think with the amount of time he was laid off, I'd be more comfortable with Johnny Evans in central defence with Vidic. Case in point, Messi's goal. He was totally left alone to head the ball in. Who was supposed to mark him? And bear in mind, Messi is so much shorter than him.
2) Ronaldo as a striker? I don't think so. Just because he can score does not make him one. He is better coming from midfield on the flanks to provide assists and crosses, and of course, the occasional shots on goal. He tried too much to score yesterday from outside the penalty box. What gives?
3) Rooney has been deployed time and again on the left supporting the central striker. I feel that Rooney's potential is better utilised in the centre, just behind the lone striker.
4) But the biggest mistake, I feel, is Ferguson's 4-3-3 formation, with a midfield consisting of Giggs, Carrick and Anderson. Bearing in mind Barca has Xavi, Iniesta and Messi, he should have deployed a 4-5-1 formation to win the midfield battle, or even 4-4-1-1. Too often, Xavi, Iniesta and Messi were allowed to roam the centre with no one pressing them.
Ah well...it was still a great game. And I'm glad that Ferguson admitted that the better team won deservedly.
