Former Man Utd captain tells Chelsea: 'If you don't have a top goalkeeper, you won't win that league.'
Frank Lampard says he is "very happy" with Kepa Arrizabalaga but Neville isn't convinced.
Manchester United legend Gary Neville doesn't think Chelsea can win the Premier League with goalkeeper Kepa Arrizabalaga.
Some fans have criticised the goalkeeper for the goal he conceded in the Blues' 3-1 win against Brighton on Monday night, but Lampard said he is 'very happy' with the Spanish shotstopper.
However, Lampard's former international teammate says the west London club will need a new man between the sticks at Stamford Bridge if they are keen to win the English top flight.
As things stand, Chelsea are close to agreeing a deal to sign goalkeeper Edouard Mendy from Ligue 1 club Rennes.
"I don't think he is [happy with Kepa]," ex-right back Neville told Sky Sports. "I wouldn't be, but, yet I know full well, having been in a coaching position, been in a changing room, you have to back your goalkeeper. You must back your players, you have to support them publicly but privately that goal, it's a really poor goal to give away.
"He conceded so many goals from outside the box last season, he's conceded another one tonight and it will cost you. If you don't have a top goalkeeper, you won't win that league.
"At this moment in time he makes far too many mistakes. He lets too many goals into the back of his net that should be saved. 19 goals conceded from outside the box - that is a sorry story for a £70m goalkeeper."
