Ben Foster has said it makes no difference to the team whether he plays in the latter stages of the FA Cup or Heurelho Gomes.

Foster has been Javi Gracia's go to goalkeeper for the Premier League this season, but Gomes has performed admirably in the FA Cup, conceding just once in four games.

However, with the Hornets now in the semi-final of the competition, speculation has started over whether or not Foster will be selected for the trip to Wembley.

"For a team like us if you're changing outfield players it can maybe make a difference," said Foster, in an interview on TalkSport.

"When it comes to the goalkeeper, I don't think it makes that much difference.

"Heurelho's at the top of his game, he's an unbelievable player and still a world class goalkeeper. It doesn't make that much difference."

Gomes was given a rousing reception following the FA Cup quarter-final victory over Crystal Palace on what was widely believed to have been his final appearance at Vicarage Road.

The Brazilian has repeatedly said that he is 99 per cent sure this season will be his last as a professional footballer, but Foster said the Watford squad are trying to convince him to keep playing.

"I still think Heurelho's got a lot to offer and we're all trying our best to change his mind," he said.

Foster discussed the issue of goalkeepers making mistakes, focussing particularly on David Martin's error that helped Brighton and Hove Albion overcome Millwall in the FA Cup on Sunday.

He reflected on his time at Manchester United and discussed how making mistakes helped him develop into the player he is.

He said: "It was a horrible mistake he will be the first to hold his hands up and say it was totally out of character.

"Hopefully he can learn from that.

"It happened to me at while I was Man United - it was probably the wrong place at the wrong time and it actually didn't work out for me.

"You have to learn from your mistakes and move on.

"When you get to my age you just feel more comfortable. You know what you are and what you can do and what you can't do."

Foster also took the opportunity to respond to recent comments made by captain Troy Deeney who suggested the keeper ate terribly, trained for just two hours a week yet still performed amazingly in games.

The keeper admitted that there was some truth to the statement.

"He's not a million miles away, I do enjoy my food," he said.

"Obviously I have to do a lot more gym work than I used to, but I've found a nice balance, life's about enjoying yourself and that's what I'm doing.

"Watford are very good with me, if I don't want to train on Wednesday or something they respect that.

"I'm in a great place at the moment."
