Manager Liverpool Jurgen Klopp confirmed that the "red" a few months will have to do without his midfielder Adam Lallana.
Playmaker suffered hip injury during the Audi Cup match against Atletico Madrid.
"Unfortunately, the damage is so serious that Adam will have to spend out of the game a couple of months, not weeks. You can almost certainly say that he will not play in August and September, "said Klopp.
Last season, the 29-year-old Englishman spent for Liverpool 31 match in the Premier League, which scored eight goals and gave seven assists.
