“Phil Coutinho is a really good football player so if we cannot use him for the next few days or weeks each team in the world would feel it,” he said.
“But it is no excuse for anything. As good as he is, he does not decide games by himself although it sometimes looks like this.

“Of course we can handle it. If he is not in you have to show – and we will show.
“Phil’s not in, Adam’s close but not in, Daniel’s close but not in – all quality players and we miss them, but you don’t look for excuses.
“We like to play football and I think the way we play it is possible without them, but it would be better when they are all fit.”
