Medical expert fears for Kral after 'very unpleasant' West Ham update

Alex Kral was “really struggling” while out with Covid at West Ham and it will take some time for him to regain peak fitness.

So says injury expert Ben Dinnery, who runs the Premier Injuries site and has a background in medicine and data analysis.

Kral, who is on loan at the London Stadium with an option to make the deal permanent, has featured just once since his arrival from Spartak Moscow.

He was ruled out for the last three matches after testing positive for coronavirus upon his return from the October international break.

As quoted by on 2 November, his Czech Republic compatriot Tomas Soucek claimed that “quarantine was very unpleasant” for Kral.

Thankfully, manager David Moyes told three days earlier that the midfielder, 23, is in a “better place now”.

But Dinnery claimed that Kral’s fitness levels will undoubtedly have dipped while he was in isolation.

He told Football Insider correspondent Adam Williams: “He was really struggling in the first three or four days.

“If he was asymptomatic, he might be looking to maintain base-level fitness away from the training ground.

“But he did miss a small chunk of training when he was away. We know that this affects the respiratory system.

“But it looks as though, physically at least, it hasn’t affected him too much.

“But he’s training away from that highly competitive environment, which is highly charged and full of testosterone.

“You can’t replicate that, even in the best gyms in the world. So yes, you’re going to see your fitness levels dip.

“But he has been able to get some kind of training in. He will have been monitored while he’s been away.

“They will also have tailored a specific programme to build him back up.”
