The winger contributed two assists in their 3-1 win against the foxes after providing one assist midweek against Benfica.
It capped off a fine individual performance from the Brazilian forward, as Mikel Arteta is delighted that he is starting to see the best of him.
“He was really good,” Arteta said during his post-match press conference. “We’ve seen that in training the last few weeks. He’s rebuilding himself and he’s not accepted the situation.
“I think he was the player who changed the game against Benfica in the last few moments when he came on, and today I think he was terrific.
“The same with the other senior players. Laca, I think the way he played, Nico grew in the game and had a big impact as well. Granit as well. A player who has played that many minutes, to play with the heart and the passion he showed in every action, I think it’s a great example for the rest of the players.”
