Chelsea might not have their long-term solution in goal with Edouard Mendy.
Although he had a fine start to life in the Premier League, the French stopper was at fault for goals against both Leeds and Everton in recent weeks.
Mendy did manage to keep a clean sheet during Monday’s clash against West Ham, but it was noted before the game that he might not be the finished article.
The duo were asked before the clash against West Ham if Mendy had solved Chelsea’s goalkeeping issue.
“We thought he had initially,” Neville said.
“Kepa was a massive problem, every shot that went on the goal looked like it was going in.
“The first six games he had five clean sheets, but in those six games he only had, I think, eight shots on his goal. What we’ve seen now in the last few games is mistakes starting to build, and he needs a mistake-free night.”
Carragher then added: “I was before these last three games.
“I must be honest, when you’ve brought him in, you’re thinking from Rennes, 28 years of age.
“It’s not late in his career, certainly as a goalkeeper, but you think could he have been spotted earlier in his career, how good is he really?
