Liverpool boss Jurgen Klopp admits Roberto Firmino is facing over a month out with a hamstring injury.

It was confirmed this morning that Firmino had suffered a serious hamstring injury.

"Losing Bobby Firmino is a blow," said Klopp.

"I don't think I need to say how big it is. It's a serious injury. We talk about weeks - more than four I consider as a serious injury. Then we have to see.

"Bobby is a quick healer."
