Team of the season
Man Utd. They clearly deserve it, no matter what happens in the final. I would give Real Madrid a shot but they failed in the last 16 of the CL for the 4th time in a row IIRC.
Most over-rated team of the season
Ok I'll rather put this as the biggest overachievers cause this one and the one belove are the same IMO. It's gotta be Arsenal. Big ref decisions against them and a lot of key injuries, and their mentality cost them any trophy this season, but still achieved more than most would have expected.
Biggest Under-achievers (can come under same as above I suppose)
I see a lot of people are putting Liverpool here, and maybe we deserve it somehow although I feel that considering all the trouble we had during the season, we've done well. But I gotta give this one to Real Zaragoza. I expected them to challenge for a CL place in Spain, but no, they're going to get relegated.
Player of the season
Crisitano Ronaldo. He still needs to step it up a little bit in big games but overall, I don't think you can argue with this too much. Torres deserves a mention too though, he came in England and made the best debut ever but scoring 24 goals in the league. He also scored crucial goals both in the league and in the CL for us, like Marseille, Porto, Inter, Arsenal, Chelsea etc etc

roud:
Young player of the season
I suppose this is the U21 category. It's gotta be Cesc, the guy was on FIRE in the beginning of the season, but got tired in the second half of the season, and you can't really blame him.
Best signing of the season
Obviously El Niño, worth every god damn penny we paid for him

roud:
Worst signing of the season (considering amount paid)
Henry. 24 million Euros for nothing.
Player you cant believe played well this season
Again, El Niño.
Manager of the season
Grant
Best Goalkeeper
Casillias.
Best Defender
Rio Ferdinand
Best Midfielder
Crisitano Roanldo (can he be considered a midfielder?)
Best Striker
Fernando Torres.
