I think Barca played wrong strat and mentality in this game, too cautious. Keita I like him but this game showed his limitations. He was just an extra man useless going forward and plugging the hole in midfield when defending, nothing more. Iniesta asked to play wide left where it just didnt happen, overlap too much with Keita so our left had nothing going. Add to that Puyol as LB. Surprised Cesc didnt feature. Messi got handled well and praise to Milan since they coped well with injuries and made chances. Lucky with the ref too. This game hopefully shows Barca does not get favoured by refs.
Return leg Barca will come out attacking and it will be completely different I think. Milan unless they play a top game will flop and lose
