2008 is our best ever team, at the very least our best ever squad. They were immensely flexible in how they could play, picking out the first 11 is a difficult task, people go for the CL starting XI but I think it was the only time that side had started together all season. Massive edge defensively, the 99 team were always chasing the games because they could never trust that backline to hold steady. Neville was a number of years off his peak, Schmeichel and Irwin were in decline, Johnsen was brittle while Berg was similar to what we have now.
It would be decided on 08 defense against the 99 attack, the waves off pressure the treble team could exert on teams. Read earlier someone saying that Tevez/Rooney was an upgraded version of Cole/Yorke, could never agree with that, only on paper, very talented pair but Cole and Yorke had the type of chemistry very rarely seen in strike partnerships.
I preferred 99 of course, and purely for the watching joy the 06/07 team inspired me more than 08, but they were a ruthless machine. Underrated now due to barca but one of the best European teams of the last 25 years.
