I think Rafa's support for Lucas really made a difference. It seems to have lit a fire. He was very good against PSV. He was good against Arsenal. I could see the effort he put in. However, while he did manage to break up play, it would seem he was always 1 step behind the play because rather than winning the ball, he was conceding free-kicks all over the place. Against Newcastle, he was excellent. Previously, he seemed afraid to try anything. He kept trying to 1-touch the ball to another team-mate or taking the safe option. In recent games, I observe that he is more willing to hold on to the ball and contribute to the overall play.
