Alexis Sanchez didn't look happy as he was substituted late on against Swansea, but the manager defended his behaviour:
"All the players are frustrated when they come off, some show it, some not.".
"I'm long enough in the job to know that. I just make the decision I feel is right, that's it. He is a good guy who gives a lot and who always wants to do well for the team."
"There's no problem. In every culture it's different. Some South Americans are a bit different to Europeans. Southern Europeans are more different to northern Europeans, you have to respect that."
"I don't look at that. I look at how well the players do that come on, how comfortable they are, because Danny Welbeck has not played for two years."
"That's much more important for me than an individual response. That is vital when a player 25 years of age, who is a regular in the national team, comes on, you have an opportunity to give him game time."
