Lionel Messi expects a different Manchester United side to the one Barcelona beat in the Champions League final in 2009 as the two teams prepare to meet in the European showpiece at Wembley on Saturday night.

Messi scored the second goal in Rome as Barca beat United 2-0 to seal a treble of Primera Division, Copa del Rey and Champions League titles in coach Pep Guardiola's first season in charge.

''I have good memories of the final in Rome, but that's in the past,'' said Messi. ''All finals are different and this will be a totally different game to that one - United have changed (some of) their players and it will be different.''

Messi also rejected claims the Red Devils are weaker than two years ago.
