If you sleep four hours happy, you're going to sleep better than eight hours sad.
It’s like I said in that interview, and I stand by it. The result of people when they are happy is 10 times better than when they are sad. For me, you have to have fun not just in football, but in life. That’s the most important thing – and Mikel Arteta has brought that back.
Working with Mikel has been great since the first day. He's always working straight to the point and he has already shown us his ideas, his goals.
