Injury expert makes Andy Robertson hamstring admission and gives Roberto Firmino Liverpool absence time frame

Andy Robertson is a big doubt for Liverpool's clash against Arsenal on Saturday.

The left-back suffered a hamstring injury in Scotland's 2-0 victory over Denmark on Monday.

What happened

Robertson reported to have felt his issue at half-time but the Scotland captained opted to carry on.

He was withdrawn with 10 minutes remaining as Steve Clarke's side booked their spot in the 2022 World Cup qualifiers.

Will he be available against Arsenal?

According to The Athletic, Robertson's chances of facing Arsenal are 50/50.

However, the chances of the former Hull defender featuring very much depend on the severity of his setback.

And Ben Dinnery - whose background is in injury data analysis and runs premierinjuries.com - believes Reds boss Jurgen Klopp may not risk Robertson.

That's because the busy festive period is just around the corner and the 26-year-old will be needed, while Liverpool have an able deputy in Kostask Tsimikas to fill the void.

Speaking on Youtube channel Premier FPL Injuries, Dinnery said: “There are question marks with regards to the fitness of Andy Robertson.

“He picked up an apparent hamstring injury during that win over Denmark.

“We're waiting on results of image, but if he comes with any sort of damage to that - regardless of severity - we'd put a big question mark over his appearance this weekend.

“We know hamstrings have a high recurrence rate.

“What Jurgen Klopp will not want to do heading into this busy festive period is risk him, especially with Tsimikas, who started the season so well in the absence of Robertson, there to fill his boots.”

Firmino time frame

Liverpool are again set to be without Roberto Firmino against Arsenal.

The Brazilian suffered a hamstring injury in the 2-0 Champions League defeat of Atletico Madrid earlier this month.

Dinnery believes Firmino will remain sidelined until the middle of December.

He added: “We've said it could be around 4-6 weeks with regards to his setback. That looks to be the case.

“No official update from the club but we're looking at around mid-December for a potential return to the Brazilian.

“That should lock in Diogo Jota for the time being.”
