If Lennon is getting the **** kicked out of him and marked out, I hardly think Walker will fair any better...me thinks you're talking **** again.
Don't think Berbatov is free, he had a clause Man Utd excercised to extend his contract another year.
If we bring on Barnetta to keep the opposition left back in check, Walker can get forward. Think of him as a more attack-minded Sandro who plays out wide instead of in the middle. We do need more battlers in our squad, just as we need a bit more variety, and he offers both. He's also another player who can take free kicks (as England noticed), although we'll soon train that skill out of him just like we did with Bale and VDV...
Drenthe anyone? Did a good job at Everton although then again so does Pienaar and look what happened there
