All players in the image above being sidelined due to injuries. Liverpool boss Jurgen Klopp has admitted Liverpool may be forced into the transfer market as the injury crisis sweeping Anfield intensified.

Philippe Coutinho and Dejan Lovren both suffered hamstring injuries in the 1-0 win over Stoke in the first leg of the Capital One Cup semi-final and, judging by the manager's reaction, both appear set for significant lay-offs. The issue for Lovren is particularly significant.

Martin Skrtel is already sidelined with a hamstring issue and with Joe Gomez rehabilitating from an anterior cruciate ligament tear, Mamadou Sakho nursing a knee problem and Kolo Toure suffering cramp at the Britannia Stadium, Klopp does not have any recognised central defenders fit.

Schalke's defender Joel Matip is a top target on his list.
