The Senegal goalkeeper has replaced Kepa as Chelsea’s first choice since his £22m arrival from Rennes in September and he’s kept three clean sheets in his first three games for the club.
Lampard’s patience with Kepa was wearing thin long before Mendy’s arrival and the Spaniard made a horrific mistake in a defeat to Liverpool earlier this season.
Mendy has injected confidence into Chelsea’s leaky defence and in a sly dig at Kepa, Lampard says the 28-year-old has proven to be ‘low maintenance’ since moving to Stamford Bridge.
‘I think what he’s shown so far has been very complete,’ Lampard said.
‘Those clean sheets have shown big parts of his game. He’s made saves in moments in games that have certainly helped us, where if the goal had gone in the games could have gone another way.
‘He’s very low maintenance, he works hard, wants to work more, and he’s eager to engage with team-mates and myself — he has a smile on his face and has played well.’
Chelsea would be willing to loan the 26-year-old in January.
