Bayern Munich star Neuer claimed Mendy was already among the top tier of goalkeepers on the planet after a strong start to life at Stamford Bridge.
‘There are a lot of world class goalies right now,’ Neuer told L’Equipe. ‘For example, Edouard Mendy, who moved from Rennes to Chelsea.
‘He is a player that we only saw in Ligue 1, who joined a big club and who was immediately successful. It’s great to see that. Overall, I’m happy to see so many good goalkeepers because we’re a brotherhood.’
But Green, who left Chelsea in 2019, doesn’t think the 28-year-old from Senegal has been playing at the top level for long enough to earn that title.
‘His rise to fame has been so quick that it’s been nigh on impossible for him to be able to nurture his game as quickly as he can do and be able to get up to speed to be called world class,’ he told Stadium Astro.
‘It was five years ago that he was in France in the queue picking up his unemployment benefit because he didn’t have a club, he didn’t have a job and he had nowhere to go. Five years on, he’s playing for Chelsea in the Premier League. It’s that quick.
‘At Rennes he had one season getting promoted, one season in Ligue 1 and you’re looking at that to say, is that enough? Is that enough to harness your skills?
‘And it’s these decisions. Decision making is about coming forward, coming out of the goal, when to come, when not to come, when to stay, when not to be involved. Doing nothing as a goalkeeper is a good option.
‘Go look at his history, go look at how many games he’s played – it’s not that many. And it’s actually a really steep learning curve.
‘So to call him world class yet is too soon purely on the basis he’s only been playing professional football for four or five years.’
Green does, however, think Mendy has a lot of potential.
Asked where he’d rank Mendy in the top goalkeepers in the Premier league, he smiled: ‘Ask me at the end of the season. You’ve got to judge a goalkeeper by a full season, that’s what I say.
‘I’d have him in the top ten but that’s the great thing: he’s got potential for so much more.
‘I think the coaching staff, Hilario, Petr Cech, the other coaches at Chelsea can go to work on him.
‘They can teach him these things and he can keep on learning while he’s playing games. He’s got potential for much, much more.’
