Roberto De Zerbi has told key players what he expects from them under his command.
And he started with three senior defenders.
De Zerbi takes charge for the first time tomorrow when Albion visit Liverpool.
He will keep changes to a minimum in his first game in charge.
But he is looking forward to putting his own stamp on the side.
He has already told players what that will look like.
De Zerbi said: “I have spoken a lot of times with the defenders, [Lewis] Dunk, [Joel] Veltman and [Adam] Webster.
“They for me are the most important players in the squad, because from them we start, they start the build-up, they start us being able to dominate the game.
“But I have spoken with Mac Allister and Caicedo on Thursday, when they got back from their national teams.
“I have spoken with March as well because, for me, Solly is a key player.
“I want him to understand why he will be important for me.
“I want him to have responsibilities that will help increase the number of goals, because I fully trust him.
“I have spoken with Trossard as well. The conversation was more or less the same as what I said to Solly.
“I have spoken with Welbeck, Estupinan, Lamptey and with the younger players.
“The day is long, 24 hours, so I have plenty of time to talk to the players, to talk about every single detail.”
He added: "Today would be the first day I can train everybody but I don't want too many changes.
"For me, it is difficult because I would like to put in my ideas but it is not right to change so much straight away.
