Horrible post and god knows where to start.
Hleb - He was signed as a back up for around £12m, made 36 appearances in the season Barcelona won the treble. Done the job asked of him in that season. Maybe a hit is pushing it, but I don't see him as a flop.
Maxwell - Are you seriously suggesting someone who was signed for 5 million euros, was sold for 3.5m and made 89 appearances(78 starts) is a flop? He was a great signing. Think you need to go and learn about 'squad signings'
Villa - A flop? A guy who scored 48 goals, made many assists, won 7 trophies. Scored in a CL final, whilst not being the main penalty and free kick taker was not a hit? Seriously?
Adriano - See Maxwell
Sanchez - Let me off with Sanchez? Are you trolling? Nobody surely can say Sanchez was not a hit or was a flop...
Affelay - Was signed for a small fee, played his part as a squad player in a successful first season, got loan fees from him. Not a flop for me, don't care that he plays for Stoke his period at Barca is all that matters!
5 hits, oh dear indeed.
