As HatterDon said, Dejagah looked very good. The third goal was set up by his play - he ended up with the ball far up the wing with no support, so he took it to the corner, held off a couple West Ham players, somehow got free and worked the ball back inside. A moment later he received another pass in the box and centered it to Rodallega (I think? My memory is going already), whose blocked shot was then squeezed in by Petric (off a defender, scored as an OG).
The only problem was that he fell down a couple times. I think the grass was slick for some reason (IIRC Sidwell lost his footing at one point, too.)
I like him. He's always had a lot of technique, but he's adapted his game a bit too. Dives into fewer tackles, and seems a little stronger physically in possession.
