Crystal Palace boss Roy Hodgson expects to call on a motivated Sam Johnstone against Leeds United.

Johnstone is being called up to replace Vicente Guaita.

“We can't make sure he is ready, he is the only one that can make certain he is ready," said Hodgson. “I would be very surprised if he was not champing at the bit to get the gloves on and get the jersey on.

“He has trained very enthusiastically for the last 10 days or so since he came back from injury, and it seems he will be more than ready – if anything he will be over ready. He won't have that lovely tranquillity that a goalkeeper who has been playing every game and getting rave reviews gets.

“He will be nervous, but we will do everything to quell those nerves because we have great faith in him. He is a great goalkeeper, and we are very lucky that if we lose Vicente we have a man like Sam with his quality and experience in his place.

“Don't forget, Sam Johnstone has been in the England squad as well, so we are not talking about a guy playing his first Premier League game. We are talking about a guy who might be a bit disappointed that he is not the No. 1 here."
