Mikel Arteta issues worrying injury update on Arsenal striker Viktor Gyokeres

Arsenal boss Mikel Arteta is concerned about a muscular injury suffered by Viktor Gyokeres, with the Gunners working to discover the severity of the problem.

The Swedish forward missed training on Monday after being substituted with the issue during Saturday's 2-0 win over Burnley.

And the £64m did not travel for Arsenal's Champions League's trip to Slavia Prague on Tuesday.

Arteta said: 'He's definitely not available (for Slavia Prague). He hasn't trained today. We need to do some more tests and scans in the next few days to understand the extent of the injury. But he's not available.

'I am concerned because he hasn't had many muscular issues and he had to do the pitch and he was feeling something.

'That's obviously never a good sign, especially for a player that is very, very explosive. 

'So we are digging in a little bit more to understand where we are in terms of the injury, and we'll announce the moment we know.'

The north London club are currently missing up to seven players through injury. Martin Odegaard, Noni Madueke, Gabriel Jesus and Kai Havertz are all side-lined with knee injuries.

Martin Zubimendi and Kepa Arrizabalaga have unspecified issues.

In his press-conference in Prague on Monday night, Arteta urged the footballing authorities to ‘respect’ Arsenal over player safety fears after his club’s request to move their Carabao Cup quarter-final clash against Crystal Palace was denied.
