Fulham boss Martin Jol says players make managers.
Jol said he was not surprised to see Andre Villas-Boas leave Chelsea, but insisted a manager's communication skills are secondary to players' performances.
He said: "It's hard if things are not going well but I have worked under managers who never spoke a word and they achieved what they wanted and nobody said anything. It's about the players, of course, you have to rely on them.
"Sometimes you have to be close and sometimes you can't - especially if you have to get rid of them.
"I always tell them if they are committed to the club and they play at least 20 to 25 games a season then I am always happy with them. Because you have to try to give them the problem as well.
"Nowadays they say they have to be happy with the manager, but I always say I have to be happy with the players as well."
