Real Sociedad coach Imanol Alguacil is delighted with David Silva's return to full fitness.

Silva trained today ahead of tomorrow night's clash with Cadiz.

Imanol said, "It seems incredible, I don't know if he has something to do with it, I'm sure it will, but with David's return today the ball ran differently. At first I would tell you that he isn't here to start playing, but I'm going to have a deep sleep and, who knows if I change my mind during the night!

"It's not a matter of the system, it's a matter of the players and their timing. Obviously, the 1-4-4-2 with David Silva is one, but the 1-4-3-3 with David Silva is also one, because there is only one David in the entire League."
