From The Daily Telegraph:
'When I played, if you won the first leg away from home 1-0 you would be in dreamland. AC Milan would have thought that a goalless draw or 1-1 at Old Trafford would have been a fantastic result, let alone a victory. Manchester United will get chances to pull the tie back in Milan but only a fool would tell you they are favourites.
Of course Manchester United regret the two good chances they missed in the first half at Old Trafford that preceded Roy Carroll's error, but the significant part of the match came in the last 20 minutes. It demonstrated the difference between the Premiership and the top level of European football.
United played really well but in that late period they looked a tired side, which is surprising because it is at this stage of a game that you would usually back them to roll over some Premiership teams. Against Milan they looked weary, a consequence of not having the ball.
When you don't have the ball, it drains you physically and mentally. Milan looked very comfortable keeping possession in the final quarter of an hour and finished the match the stronger.
United will be climbing a mountain in the San Siro tomorrow. There are parallels with the Juventus game in 1999 when, having drawn a Champions League semi-final 1-1, United went 2-0 down in Turin before dragging themselves back to win 3-2. You would never bet against them doing something similar but Milan are a better side than Juventus were six years ago.
United are adept at going away from home, sucking in the opposition and then hitting them on the break, but Milan will be a very difficult team to suck in. They have their goal and they will be happy to sit back and let United come on to them. To penetrate that defence will be an enormous task and if United go through, it will be one of their great European achievements.
United are at least capable of grinding out a result, which Arsenal seem not to be. Every football team at every level have weaknesses but the key is to hide them. If it is your full-back you can provide cover, either by doubling him up with a wide midfielder or asking the centre-half to move across.'
