"When we played Barcelona away, in 2008, I remember playing right wing, with Owen Hargreaves at right-back and we had Abidal and Iniesta against us. I remember thinking: 'Jesus! I've got to do this.' It was a long night, but we defended very well, we got the 0-0 and then won 1-0 in the return. Just having that discipline about your game can be the difference in whether you win the trophy or not."
