Sunderland manager Roy Keane has warned his players that a number of them are playing for their futures in the final two games of the season.
The Black Cats secured their Premier League status with a 3-2 victory over Middlesbrough last weekend.
But ahead of meetings with Bolton Wanderers and Arsenal, Keane has issued a stark warning to several members of his squad.
"The players have always got something to prove to me," he told the club's official website.
"There will be decisions made over the next week or two on certain players - on their contracts and the like. They will be under review.
"We want to finish the season on a high because I know that, if we were to lose our next two games, it would put me in bad form, I don't want that.
"People might think we're off celebrating and that Bolton will take us for an easy three points - hopefully no team of mine will ever not give their all.
"If I thought for one minute that people were taking their foot off the gas, I'd see it as an insult to me, an insult to the football club and an insult to the supporters.
"We've not had many victories in the Premier League this season, and only two away, so let's try to get another one."
