Jurgen Klopp says losing star defender Virgil Van Dijk to injury is a "big blow" for the side. The centre-back is facing a month on the sidelines after a hamstring problem was found to be more serious than first feared.The Liverpool manager said the "harsh" diagnosis came as a surprise to the team as he "didn't feel a lot" at the time. However, he did say that he is excited to see "natural" Cody Gakpo in action, as he is a "joy to watch."Source: PA
