Alex Oxlade-Chamberlain: Liverpool midfielder suffers 'really bad injury'

Oxlade-Chamberlain scored in the 3-0 win against Manchester City in Liverpool's Champions League quarter-final first leg

Liverpool midfielder Alex Oxlade-Chamberlain appears to have suffered a "really bad" injury during Tuesday's 5-2 Champions League win against Roma, says manager Jurgen Klopp.

The England international, 24, was taken off on a stretcher in the 15th minute after appearing to hurt his knee when challenging Aleksandar Kolarov.

"It's probably a really bad injury," Klopp told BT Sport.

"If you can say that already before the scan then it's never good news."

Oxlade-Chamberlain has enjoyed an impressive debut season for Liverpool since joining from Arsenal for £35m last August.

He has made 41 appearances in all competitions, scoring five goals.

A long-term injury could put in doubt his availability for this summer's World Cup, which gets under way on 15 June.

Liverpool midfielder Georginio Wijnaldum, who replaced Oxlade-Chamberlain during the semi-final first leg, said: "I just spoke with him in the dressing room and what the manager said is difficult.

"We still have to see how bad it is. I hope it will not be that bad and he can still go to the World Cup."

Liverpool full-back Trent Alexander-Arnold says the players will be determined to reach the Champions League final for the midfielder, if his injury is serious.

"Obviously we're all gutted for him," he said.

"If he can't play, we'll be looking to secure the place in the final for him and the other lads who can't be involved."
