Yeah, he clearly faded, but I am convinced that had to do with how he spent a great deal of time running up and down the flank. He should play further back, he was doing too much winger duties. He doesn't have great stamina and was always best at playing in midfield, not sure what's the point of starting him in the wings. Even if he often makes moves in, that's still way too forward for him to deal any serious damage imo.
