Manchester United boss Ralf Rangnick has confirmed Chris Armas is joining his coaching staff.

The former Toronto FC coach has been cleared to make the move.

Rangnick said today: "Very happy to work with staff I met last week, they gave me a lot of help.

"We have decided to bring in sport scientist with Sasha Lense, he will be introduced as soon as he has visa and work permit.

"I will also have another assistant coach with Chris Armas."

He also said, "Actually I don't know the situation in other clubs. In Germany most clubs has a sports scientist. For me it is absolutely logical.

"For me it is only a question of logic. Should have an expert for the brain. Not to put them on the red sofa and holding hands with the players, but for helping the players that the brain should assist the body. Everybody in our team should think in the right way."
