Rooney struck twice in the 2-1 win.
"Wayne is important for the team," said the centre-back. "He is working hard. Obviously, he scored the goals and I think the more games he plays, the better he is. We need him, especially for the second half of the season, as we need all the players to be fit. We have a good squad now and it's going to be hard for the manager to choose the first XI."
