On the back of three consecutive defeats, Real face Recreativo Huelva tonight, while in-form Barca will be in Madrid for their clash with Atletico.
"I feel the same as always, I am not concerned at all who will be a leader on Sunday, I am concerned about winning the championship, not what happens week by week," said Schuster. "We know that three weeks ago we could not win the League, not tomorrow either, it will be won in time, regardless of who is leader before.
"We must seek victory and the rest is irrelevant."
"They both give us presence and character. I hope to give them some minutes (tonight) so they can pick up the pace and then move onto Wednesday."
