West Ham boss Slaven Bilic says winning is key to a happy locker room.
Bilic isn't afraid of cracking down on his players when needed.
"If the results are good, nobody will moan. They will even ask for more because they love to win games," Bilic told the Daily Mail.
"They love to be popular, they like to be praised by TV pundits or the press, or if they go to a restaurants, they are recognised with a thumbs-up or a well done.
"They like winning so if your methods work for that, they will give it a try even if it is different. It is all about the balance, if you over-train of course you have problems. But if you train well, if you give a little bit of gas, you are OK."
