Ben Foster was left questioning the effort of some of his Watford teammates after their relegation to the Championship was confirmed on Saturday with a 1-0 defeat at Crystal Palace.

The goalkeeper made several important saves during the match to keep the score down, but was beaten by a Wilfried Zaha penalty during the first half that confirmed the Hornets would not be in the Premier League next season.

After the match he said that the team had been inconsistent in their efforts and that too many players in the squad were guilty of slacking off before the end of matches.

“You just don't really know what you're going to get from us, to be perfectly honest,” said Foster. “We've got too many players who are happy to put it in for an hour, 70 minutes, but then probably fall off and happily let it go in the last 20 minutes.

“You can't have that. When you're a team like us, the minimum is giving it everything you've got. The ability you can forego a little bit and you can accept that you might not have the quality of some players, but you've got to put the effort in.”

Separately, in a post on his Instagram page, the 39-year-old described the current season as one of the worst in his career, while also defending himself, saying he had given "absolutely everything".

Foster also spoke about his future, with his contract at Vicarage Road set to expire at the end of the season.

"This season has been rotten. One of the worst in my 20 year career," he wrote. "The toll it’s taken on fans, staff and players will take some time to heal, but now’s the time to put all our focus on having another top-class Championship season next year to get this brilliant club back up into the big leagues.

"I know a lot of people think that because I walk around with a smile on my face, failure and relegation doesn’t bother me, it does, but I also know that as the old man of the team, it’s my responsibility to help the younger players recover from setbacks and poor results as quickly as possible.

"I will always hold my head high knowing I’ve given absolutely everything I’ve got, both on and off the field to help myself and everyone around me to be a success, I don’t know what the future holds for me, but I've gotta say, @watfordfcofficial will always have a special place in my heart."
