Liverpool's hopes of defending their first Premier League title took a turn after their star defender Virgil van Dijk suffered a knee injury during the Merseyside derby.
Van Dijk clashed with Everton goalkeeper Jordan Pickford and was forced to limp off the pitch after just 11 minutes, with Liverpool later confirming he had damaged the anterior cruciate ligament in the knee.
So will he be forced to miss the rest of the season? Goal takes a look.
