Chelsea winger Christian Pulisic will miss at least four weeks to injury, reports say.

The American hobbled off with a hamstring injury in the FA Cup final defeat to Mikel Arteta’s Arsenal over the weekend and is set to miss the rest of the 2019/20 season.

TalkSport claim the Blues will be without Pulisic for their Champions League decider versus Bayern Munich this weekend and will only just return to training when the new campaign begins.

Pulisic is expected to miss between four and five weeks because of the injury.

The Premier League have pencilled in 12 September to kick off the 2020/21 term and Pulisic is in a race against time to be fit for his side’s opener.

Pulisic has been Chelsea’s star man in the latest weeks and scored the Blues’ only goal in the 2-1 defeat to the Gunners in the FA Cup final.

The 21-year-old ace posted a short update on his Instagram after picking up the injury but assured Chelsea supporters it would be a short lay-off.

Frank Lampard has bemoaned the amount of injuries his roster has picked up in the last month, with Christian joined by Cesar Azpilicueta and Pedro in the treatment room.

The former Barcelona man underwent surgery on his shoulder this week which brings a close to his five-year stint at Stamford Bridge having already agreed to sign for Roma when his contract expires.

Meanwhile, Chelsea have reportedly joined the race for Real Madrid left-back Sergio Reguilon.

Everton and Sevilla are also understood to be keen on the 23-year-old Spaniard after he impressed on loan in Andalusia.
