Gary Neville believes Mignolet would have stopped Jagielka’s Merseyside derby goal if he hadn't adopted an unusually position when the shot was struck by Phil Jagielka.
The Sky Sports pundit said the goalkeeper made similar mistakes last season and says he needs to stop the unusual low stance he has adopted.
“I’d seen it last season and didn’t mention it then and then I saw it on Saturday on thought that it’s a pattern,” Neville said.
“It’s a technical error for me, the way in which he is crouched down, and that’s the reason I mention it.
“It’s three goals in big games. There might be more, but those are the three that I remember, particularly on Saturday because it was such a big moment in the game.”
