Sunderland boss Gus Poyet has warned their summer signings they must fight for their place.
Poyet has hinted he needs to see more on the training pitch from his foreign players.
He said: "It's the manager's prerogative, the decision of the manager,
"I came here and tried to analyse the quality of the players and the squad and, depending on what I think for Sunday, I will pick those players.
"I don't think 'he's been here for five years' so I'll pick him or 'he's been here since the summer' I'll pick him. It's all the same for me.
"The ones who are performing stay on the pitch, the ones who don't are out. I have two players out for three games. There are two positions to grab because of that.
"If the players who come in play then Andrea and Lee have a problem.
"It's not depending on me, it's depending on the players who're coming in. If they don't perform then the others have a chance to come back. For me, it's one team, one group and it doesn't matter where you come from, if you're tall or small, fat or skinny you are the same.
"If I need you then you play. I don't analyse if you were here before the summer or not."
