Brendan Rodgers has explained why Adam Lallana will be given time to recover from a knee injury that is expected to rule the midfielder out of the start of the upcoming season.

The 26-year-old sealed a switch to Anfield at the beginning of the month and travelled with the Reds for their summer tour of America, starting in Boston.

But having trained with his new teammates for the first time at Harvard University earlier this week, the playmaker suffered a lateral collateral ligament knock.

Injuries of that kind can require up to six weeks on the sidelines, and the manager has no intention of rushing the No.20 back, taking a broader view of the future.

"Of course it was very disappointing - it's probably going to be four to six weeks," Rodgers said at a press conference from Soldier Field in Chicago.

"He has looked fantastic in training; it was just a very simple exercise with no pressure. The medical team are looking closely at that at the moment.

"We're hopeful that he'll come back fairly quickly, but there's no rush. He's a fantastic player, we just need to get him back fit and well because it's a long season."
