Claudio Ranieri says his Leicester City players must fight to prove their worth before his mind can turn to the January transfer window.
The Premier League champions have struggled in the league this season, where they currently lie 16th in the table, and were then thrashed 5-0 at Porto in the Champions League on Wednesday.
"Everybody at the club has a job, and, of course, the recruitment area is working very hard," he told a pre-match news conference ahead of Saturday's game against Manchester City.
"They wait for me to say: 'OK, now I need this, this and this'. Until then, I want to check my players.
"We have to fight. Only the players who want to fight until the end will stay with me."
"I made these changes because I could do this - Guardiola also made changes," he said. "So why not make changes when your players are tired? Why not give the opportunity to the other players to show what they can do?
"Now we have to be focused on these matches until Christmas day. We need points and we have to fight."
