Watched the match again. Once Anderson settled into the match, we were much more balanced defensively and offensively. I'm not sure where this myth comes from that he mostly performed well because QPR tired. He came on at 58 minutes. If QPR tired that early into the match, I would be worried about their fitness and it wasn't until the 70 minute mark when there was a noticeable change in QPR's play. At that point, the wind was knocked out of their sails and their attacks became much more sporadic.
A tactical point to keep in mind. The next time you lot watch Anderson, watch how he drags the opposition midfielder wide and out of position. He did this on several occasions Saturday and it was simply fantastic. It opened up space for Fletcher and our other attackers to move and find angles to penetrate QPR's defense. Basically he would start from a wide midfield position, pass to whoever was occupying the hole, receive the ball back, dribble diagonally through the center of midfield, lay it off to a teammate, then continue his run wide. At some point he would check his run, but it was wide enough to where one of QPR's midfielders had to track him. Combined with our increased tempo, it opened up the game and gave us more impetus through the center. The analysis is a bit simplistic but it was one aspect of his performance which stood out to me.
