Before the game against West Ham United, Chelsea coach Maresca was asked whether Estewan would start in this game, and he hinted that there was such a possibility.
Maresca said: "Since joining us, he has performed very well and performed well in training classes. But for me, it's a process, he's still young, so we need to be cautious. Considering his performance against Crystal Palace, he can be a starting option tomorrow, but we will also consider today's training and then make a decision."
Maresca also mentioned Andre Santos, saying: "I'm very satisfied with Andre and I'm very happy that he stays here. He can play Enzo and Caesedo's position. He had a starting point in the Club World Cup, against Palmeiras, and he was as a No. 6 player performed very well. So, he can do both positions well, which is a good thing. "
"I always try to play the same way, that is to decide who will play through daily training. Of course, every few days is going to play, so there is a rotation. Last year at Europa League, especially in the beginning, we changed 10 to 11 players in each game, and this season in the Champions League, we can't do that."
" But no matter what, we need to change players because they can't play 60 games. So, once their form has declined, we need to have other players ready."
