Graeme Souness has questioned whether Daniel Sturridge has the work ethic or mentality to become first choice at Liverpool.
Sturridge has found himself down the pecking order of strikers at Anfield this season, with the Englishman starting just four games of a possible 11 in the Premier League.
He is yet to find the net in league action, with Roberto Firmino, Sadio Mane and Philippe Coutinho more often entrusted in forward roles by Jurgen Klopp.
Writing for The Times, former Liverpool midfielder and manager Souness has questioned the 27-year-old’s mental and physical capabilities.
“As we saw with his goal, Sturridge has that quality, but what he does not have, and which all successful teams want, is a work ethic,” he said.
“That explains why two big clubs, Manchester City and Chelsea, have let him go and why he is now not in the starting team at a third big club, Liverpool.
“He signed for all three before his 24th birthday, so there have been some good judges who have doubts about him.
“Sturridge is 27 now and I would suggest he’s not going to fulfil his potential.
“He either cannot maintain physically, because of his well-documented injuries, or does not want to mentally put in the shift as a team player that Jurgen Klopp demands.
“Liverpool’s manager sees him as substitute, a get-out-of-jail card who comes on with 20 minutes left.
“You would put him in ahead of Roberto Firmino for quality, there’s no argument, but the Brazilian works harder.”
