Liverpool forward Roberto Firmino may return for the defending champions against Arsenal this weekend but skipper Jordan Henderson has yet to resume training, manager Juergen Klopp said on Friday.

Firmino, who has six goals and five league assists this season, missed Liverpool’s last three games due to a knee injury while Henderson has not played since late February after undergoing surgery for a groin injury.

Klopp added he was not sure if either Henderson or Dutch defender Virgil van Dijk, who has been sidelined since October with a knee injury, would be available for the European Championship this summer.

“Bobby (Firmino) is back. All the others are not and I have no idea about the Euros,” Klopp told reporters ahead of Saturday’s trip to London.

“I don’t want to take a player away from England or Holland. If they’re ready, they’re ready (for the Euros).”

Liverpool and Arsenal have had poor league campaigns, sitting seventh and ninth in the standings respectively with nine games left to play. The two teams are separated by four points and Klopp said he was wary of playing Mikel Arteta’s side at the Emirates Stadium where Liverpool have not won since 2016.

“Arsenal are a quality side... there’s a lot of potential and quality already and they have the experience of youth,” Klopp added.

“They are a really exciting team but the Premier League is a tough league and if you’re not at the top level, you get punished. It’s a tough one, but it will be a tough one for Arsenal as well. We want to be a team Arsenal do not want to face. We have to fight with all we have.”
