If you whoop and holler all the time, the players just get used to it.
There's a lot of players that go to a city, pick up a check, go to practice, and just worry about what's happening in their households, and you can't blame them.
Don't get me wrong; it's not like I didn't go out and have fun. But there's been a lot of players that come to New York and get caught up in the lifestyle, and before you know it, they're sent away to another team because it affected their performance.
Sometimes in a game - even with the best will in the world - a striker can drift out for 10 minutes and then come back into it.
I have to get used to international management. The players will go back to their clubs, they will all be playing at the weekend, they will all be thinking about other things.
Messi often has a crowd of opponents around him, but with Neymar on the pitch, too, at least two of those opposition players will have to be aware of him.
A player's mentality is very important. The five or 10 per cent where they're not focused because of wanting to go somewhere is enough for them to haul off their quality. It impacts on everything. So, as a board and manager, you have to make a decision.
In Serie A players have to stay in a hotel before a home game to ensure proper preparations without the distractions a wife and family can bring. It's a system which no doubt suits some players, but would not be my choice.
