The Brazilian playmaker had to be helped off the pitch by two members of Villa’s medical team after going down late in yesterday’s 4-0 win over Everton.

Coutinho, who missed a large chunk of last season with hamstring problems, will undergo a scan today to confirm the extent of the damage but Emery’s initial prognosis was positive.

He said: “I don’t think it is a big injury. I think it is a hamstring but we have to wait for tomorrow to analyse. Then, hopefully in two or three weeks he will be available again.”

Coutinho’s injury was the only blot on an otherwise excellent afternoon for Villa, who recorded their biggest win since Emery took charge.
