Rangers manager Pedro Caixinha says he would resign if he did not believe his team could win against Celtic on Saturday.

Caixinha is hoping to bounce back from a 2-0 defeat against Brendan Rodgers' side in the Scottish Cup semi-final to hand the Scottish champions their first defeat in domestic competition this season.

He said he has confidence in his players and the fact Rangers have nor won against Celtic in five attempts this season was irrelevant.

"That belongs to the past," he said.

"The present and the future is Saturday's game. If there's wasn't [belief in the squad] I would not be here facing you.

"If I don't believe that I can do these things I'm not going to show up. I would just resign and go home."
