Liverpool forward Diogo Jota is a doubt for Saturday’s trip to Watford after he was sent home early from international duty.

The 24-year-old returned to Merseyside before Portugal’s World Cup qualifier against Luxembourg on Tuesday having not trained with the squad since being left out of this past weekend’s friendly win over Qatar due to a muscle injury.

“Diogo Jota was dismissed by the national team manager Fernando Santos, after being considered unavailable by the FPF Health and Performance Unit to face Luxembourg, in a meeting to be held this Tuesday,” read a statement from the Portuguese Football Federation.

“The Liverpool player, who has already left the stage of the national team, has done conditioning work since the beginning of the international break, having also missed the match against Qatar.”

Liverpool’s match at Vicarage Road could also have them line up without goalkeeper Alisson Becker and midfielder Fabinho as they are not due to arrive back in England from Brazil duty until late on Friday.

Manager Jurgen Klopp has had some good news on the selection front with Trent Alexander-Arnold returning to training.

The England right back missed the last two matches with a groin problem but was pictured at the club’s training base working alongside members of the first-team squad who are not on international duty.

However, midfielder Thiago Alcantara – out since 18 September with a calf injury – was not pictured in the workout.
