“He is saying ‘you should be five yards to the right’ and we are able to see things that are happening live on the pitch.
“That kind of scrutiny is new to every single player. The case before was that as long as we got the results everything was fine.
“David Moyes would have looked at videos a lot so we got a bit of that from last year. Now we are looking at things in greater detail.
“That is the standard he has set for us. It is everything from the clothes you wear to the time you have a meal and everyone eating together.
“He is quick to congratulate you when you have done well and is also quick to tell you when you have done something wrong.”
