#3 Manchester United (2007/2008)
Sir Alex Ferguson built so many great sides in his time at Old Trafford but his 2007/2008 version may just be his best ever. This triumph would be the second of 3 league wins in a row for the club but it was the best season by far. They added the Champions League trophy to their league one, beating Chelsea after a penalty shootout.
Cristiano Ronaldo was the undisputed star man of the team: after an outstanding 2006/2007 season, he somehow managed to outperform himself this time round, scoring 31 goals, an amazing tally for a left winger. This was the season where he truly announced himself as one of the 3 best players in world football. His dribbling ability, free-kick taking, link-up play and finishing were a joy to watch for fans.
Ronaldo also formed 1 part of one of the best attacking trios in recent history, with Wayne Rooney and Carlos Tevez bullying and outfoxing defences with him. The rest of the team had no weak links either, and even lesser-heralded members like right back Wes Brown and centre midfielder Michael Carrick performed admirably well.
Ferguson could also claim to boast perhaps the finest Premier League centre-back pairing ever in Rio Ferdinand and Nemanja Vidic. They represented such a great balance: Ferdinand the silky ball-playing defender, Vidic the rugged, fierce physical threat. Often, they were too much for opposition strikers to face.
It says so much about this side that many say they're better than Ferguson's other classic Manchester United side, his 1998/1999 treble-winning team with of David Beckham, Andy Cole, and Roy Keane; in 2007/2008 they were just that good.
