Sherwood could not contain his frustations after Spurs suffered a 4-0 Premier League humbling at Stamford Bridge, suggesting that his players are too 'nice' and will easily forget the result.
Spurs are preparing for Thursday night's Europa League last-16 tie at home to Benfica, which will be followed by the visit of north London rivals Arsenal on Sunday.
Another defeat to a capital club would further test the patience of Tottenham's fans and Sherwood has warned his players to demonstrate their desire to stay at White Hart Lane - or risk being offloaded in the summer
"There are a lot of players here now who are playing for their future and I think they realise that. I will have a good look at the whole squad and see who I need to keep and who I need to bring in," said Sherwood.
"I want players here who want to play for the club and they've got until the end of the season to show they are playing for the club and not for themselves.
"I don't think at any football club, a player should be doing a club a favour by playing for them. You'll see a lot of players all over the world, sometimes they think they've outgrown the football club, but people pay a lot of money to watch their clubs and it's in their blood and players owe to them to perform 100 percent for the shirt."
