Arsenal head coach Mikel Arteta explained why Leandro Trossar was restrained in his celebration after opening the scoring in the 2-0 win over Aston Villa in the Premier League match.
"When you are not in the starting lineup, there are some ways to react. Leo is upset, but he is upset and he shows on the field how good he is. This is a huge quality. He acts the same way despite not being in the starting lineup.
This is a great example for the rest of the team and for me personally. We have two great left wingers and we know we will get quality from both of them," Arteta was quoted as saying by Goal.
