Emre Can remains a major fitness doubt for Liverpool’s Premier League trip to Crystal Palace after missing Thursday’s session at Melwood

However, the good news for Jurgen Klopp is that Andy Robertson was fit to train after being forced off playing for Scotland against Hungary with a dead leg.

Joe Gomez, who suffered an ankle injury on England duty, and Can were the only significant absentees as Klopp put his full squad through their paces for the first time since the international fixtures.

Can continues to have treatment on the back problem which forced him off against Watford a fortnight ago and then ruled him out of Germany’s two friendlies.

If the midfielder misses the contest at Selhurst Park then James Milner or Alex Oxlade-Chamberlain will replace him.

The potent front three of Mohamed Salah, Sadio Mane and Roberto Firmino all trained fully after reporting back to Melwood unscathed following their international commitments.

Trent Alexander-Arnold was also involved and is available for selection. The teenager’s absence from the England Under-21s squad to face Ukraine on Tuesday sparked concerns about his fitness.

However, Aidy Boothroyd simply opted to give him a breather after playing 90 minutes against Romania three days earlier.

Klopp must decide between Alexander-Arnold and Nathaniel Clyne at right-back against the Eagles.

Clyne is eyeing his first appearance of the season following his recovery from a long-term back injury.

Highly-rated teenagers Rafael Camacho and Curtis Jones were also part of Thursday's session at Melwood.
