Antonio Conte has warned Tottenham players to improve or they risk being left out of the team following the dismal 2-0 loss to Sporting Lisbon in the Uefa Champions League.
Tottenham missed a series of chances, with star striker Harry Kane the major culprit in Portugal.
The Italian manager has made it clear that such a performance will not be tolerated by his stars.
"There are no players that are undroppable.
"This has to be very clear," Conte told reporters on Thursday.
"If I am telling this, it is only to protect my players and to give them the possibility to be, in every moment, at the top.
"Then you know very well you can play one game well, another you can score, another not, but my task is to try to protect my players and to protect the team.
"In the Champions League, they are always massive games, and for this reason, I need to have all my players available.
He also reiterated the need to have all his players available for selection.
"I need all my players available for rotation to be in every moment ready when I call them to play and to play well for the team, for the club, for the fans, for everybody."
The former Chelsea coach is expecting a response from his team when they take on winless Leicester City in the Premier League on Saturday.
"For this reason, we have to be a bit angry, to try and have a good reaction because now we have the possibility to play another game in the Premier League, and for us, it's important to get a win," he said.
"At the same time, you know you're playing against Leicester. We are talking about Brendan Rodgers, who is a really good manager, who won a lot in his career, so for this reason, we have to pay great attention."
Tottenham are unbeaten in the Premier League this season, winning four and drawing two of their first six games.
