Leeds United manager Marcelo Bielsa says he hopes Aston Villa captain Jack Grealish is available to face his side at Elland Road on Saturday.
Grealish was absent for Villa's 2-1 defeat by Leicester last weekend with a leg injury and it is unclear when he will return to Dean Smith's side.
Argentine Bielsa said Grealish, 25, is "a great player who can unbalance you".
However, he added that the presence of talented players such as Grealish in an opposing side can act as a "stimulus".
Bielsa added: "I always prefer that opponents have their best players available because even if that fortifies a team and makes them more scary to face, it's also a stimulus for us to face such players and to try to neutralise them.
