Liverpool make the trip to London on Sunday afternoon to take on Premier League leaders Arsenal at the Emirates Stadium, and Jurgen Klopp has delivered some new injury news ahead of the clash.

What's the latest?

The Reds manager took to his pre-match press conference to reveal that deadline day loan arrival Arthur Melo has sustained an injury and will not be available to feature against Mikel Arteta's side this weekend.

Klopp told the media (via This Is Anfield): “There’s one new injury – Arthur in the last session before the Rangers game.

“In a normal situation, he just injured a muscle. We have to wait for further assessment to wait for how long it will be.”

Klopp should be frustrated

There is no doubt that Klopp should be frustrated with the latest injury to a midfielder in his squad, especially as the Juventus loanee was meant to come in to add depth to an already depleted position.

Naby Keita, Curtis Jones, Jordan Henderson, Thiago Alcantara and Alex Oxlade-Chamberlain have all suffered from various injury issues over the season so far, and it was the Liverpool captain's injury blow against Newcastle United at the end of August which prompted the deadline day signing of Arthur.

Liverpool's ongoing injury issues have been a contributor to the terrible start to the Premier League season we have seen so far from the Reds, with Klopp's side currently ninth in the table and 11 points adrift of their upcoming opponents at the summit already.

As a result, the new injury blow to Arthur will surely annoy his manager, who still has six fixtures to plan for over the rest of the month, including a league clash against Manchester City on Sunday week and  their Champions League games against Rangers and Ajax.

Arthur has barely been seen in action since his move to Merseyside in September, featuring for only 13 minutes in the first team against Napoli which ended in one of Liverpool's heaviest defeats in the Champions League to date, Therefore, if Thiago, Fabinho and Henderson can remain fit and fresh for Sunday, it would likely go unnoticed that the midfielder is absent.

With that being said, Klopp must hope that his current crop of available midfielders can maintain their fitness throughout this congested month of fixtures, as losing another player in that position could be even more detrimental to Liverpool's stop-start season.
