Tottenham boss Mauricio Pochettino says Lucas Moura has made a positive impact on his new teammates.
And Pochettino did not rule out the 25-year-old Brazil international making his first Premier League start in the visit to Crystal Palace.
He said: "We need to assess him because he played 70 minutes after a long spell out. Tomorrow we have another training session, we have 24 players in position to be selected. We need to assess everyone.
"I was happy with his performance (against Rochdale), and his attitude and capacity to adapt to group and team. It is not easy for a player who doesn't play for seven months and comes to a new team and everything is new.
"I am so happy, the player is so happy, and his team-mates are so happy with him. He is so humble and works hard every day to improve. And then he is a quality player and we hope he can show his real quality with us."
