Leeds meet Villa this weekend.
Bielsa said today: "On one side he is a great player, a player who can unbalance.
"I always prefer the opponent has their best players available because even if that fortifies a team, the best players make their teams more scary, more difficult to face. They're also a stimulus for us.
"To face such players who are playing so well, to neutralise them, looking to impose yourself on an opponent with their best players and not debilitated. Like I said before, they're a team with players to cover any absences."
