The Dutch goalkeeper told manutd.com: "Our attack scored lots of goals and caused problems for the opposition. Just look at the goals scored by Wazza [Wayne Rooney] and Carlos [Tevez]. But the midfield was also impressive. The manager had many options and changed the side to suit the opposition.
"They all did so well there. Scholesy was missing for a few months, but players like Anderson, Michael Carrick and Owen filled in. There's so many good players. And in the matches they needed to help the defence, they put in the extra shift. We defend as a team and attack as a team. All season we fought for each other, whether that was to score a goal or to keep a clean sheet."
Van der Sar added: "Team spirit does play a part, yes. Just like this club always has to try and play nice football, the attitude is always that we're a team and will achieve together. Sometimes you go out and it doesn't always work - the opposition goalkeeper is very good or you miss your chances. But you just have to keep going and fight for each other until the final whistle."
