Estevao Willian appeared to suffer a hamstring injury during the first half of Chelsea's clash against Manchester United. The 18-year-old winger pulled up after chasing a lofted pass behind the opposition backline, and was forced to come off.
After receiving some on-field medical treatment, Estevao signalled to the bench that he was unable to carry on. Liam Rosenior immediately turned to Alejandro Garnacho, who leapt out of the dugout to do a quick warm-up.
Estevao limped off the pitch and headed straight down the tunnel. As it stands, the severity of the potential injury remains unclear, and the Blues boss will be expected to provide an update on the situation after the game.
The Brazil international has only recently returned to action following a spell on the sidelines with a muscle problem. At the end of February, he tweaked his hamstring in training ahead of Chelsea's clash against Burnley.

Estevao was out for a month, missing four Premier League games. He marked his long-awaited return with a promising cameo off the bench during the 3-0 defeat to Everton before making his first start in nearly two months during the 3-0 loss to Manchester City.
Unfortunately for the Brazilian teenager, he didn't have the desired impact on Saturday night, coming off after a quarter of an hour. Speaking to reporters at Cobham on Friday afternoon, Rosenior previewed the clash against Manchester United.
