The Manchester United legend was not impressed by the defender's performance on Sunday afternoon.
The defender replaced captain Vincent Kompany at half time during the 4-2 loss to Manchester United in the Manchester derby on Sunday afternoon, but was unimpressive in his display.
In fact, the Frenchman was at fault for Chris Smalling’s headed goal as he inexplicably played the United attack onside to allow them to score while the rest of his team tried to play an offside trap.
The display at Old Trafford has now led to criticism from the former United full back.
“Mangala doesn’t know the game, he doesn’t know how to play the centre back position,” said Neville.
Mangala has endured a difficult time in England since his big money move from Porto in the summer; with his new side having failed miserably to defend their Premier League title.
In fact, the defender has failed to settle at all into the City side and has spent a vast majority of the season on the bench, with veteran Martin Demichelis preferred alongside Vincent Kompany.
Now, Neville has suggested that Mangala will always be caught out against best tactical teams out there.
“If you’re talking about a team that can tactically cause you a problem, he will just go and chase,” he added.
“Rather than being patient and holding his own, he will go and chase people into different positions where he shouldn’t be.”
