BOSS Patrick Vieira will make a late call on Tyrick Mitchell and Michael Olise ahead of Sunday’s FA Cup semi-final with Chelsea.

Olise sustained an injury during international duty with France’s Under-21s last month while left-back Mitchell was forced off in the weekend loss at Leicester with a minor calf issue.

Vieira revealed both took part in training on Friday but had to wait to see how they reacted on Saturday.

He said: “We had Tyrick and Michael, who had some training on the field individually yesterday and a little more today.

“Of course then we have to wait until tomorrow to see any reaction but they will only get involved in the game if they are 100 per cent fit.”
