Klopp highlighted Lovren’s prolonged World Cup involvement as an exacerbating factor in the Croat’s fitness issues.

“Now in the World Cup, [playing] three times [for] 120 minutes it got a bit worse, but I am pretty sure it will settle in the next one, two or three weeks. In that time he can probably for sure train already, but not the full programme, so that will then take time.

“In the end, it is serious but not that serious, so it’s not that we need to be afraid that it will take him until whenever. In the moment he is not available, that’s true.”

Liverpool coped well without Lovren on Sunday, convincingly beating West Ham 4-0 at Anfield with Joe Gomez filling in at centre-back alongside Virgil van Djik. Lovren hasn’t featured for Liverpool since their Champions League Final defeat to Real Madrid on May 26.
