Antonio Conte hailed the performance of Cesc Fabregas against Leicester but says he is not guaranteed to face Arsenal this weekend.
The Spain midfielder scored twice in extra time to cap the visitors' recovery in the EFL Cup third round as they won 4-2, having fallen 2-0 down inside 35 minutes.
Fabregas is yet to start in the Premier League under Conte, with his only other start in the EFL Cup win over Bristol City last month, with Nemanja Matic, N'Golo Kante and Oscar preferred.
But a gritty display from the 29-year-old - ahead of Saturday's visit to former club Arsenal - impressed Conte, although he offered no assurances he would start at the Emirates Stadium.
"I want to win and my choice is done to win," Conte said. "I don't care what their name is. For me it's important when I call someone to play and they show me my choice is not wrong.
"All the players in my squad are a possibility to play against Arsenal. There are three days before the game and they have the opportunity to convince me to put them in.
"I am pleased for Cesc because he played a good game, he showed me great commitment in the training sessions. I am satisfied when I see this behaviour.
"This is the right way and I want my players to create good competition and, game by game, give me the opportunity to choose the best line-up."
