He won the continental treble at Inter Milan. He then went to Real Madrid, which is where I think it started to go wrong for him. He became Pep's rival in Spain, and we all know how that went. Pep's Barca is considered one of the greatest club sides ever to grace the game. He would publicly try and start fights with Pep through the pro Madrid media, but despite a title and I think a cup win, he came out a poor second in that spat. He went to Chelsea and won the title again, but was quickly sacked the next season when they looked in relegation trouble. He then engaged in his second rivalry with Pep by going to Trafford. He came off even worse this time.
