The signing of an elite goalkeeper is a landmark moment in any manager's tenure at a major club. Frank Lampard needs the impending arrival of Edouard Mendy to be exactly that for his reign at Chelsea.
After another error from Kepa Arrizabalaga in Chelsea's 3-1 win over Brighton, Gary Neville warned that, for all Lampard's eye-catching spending this summer, a failure to sign a commanding No 1 could eventually be his downfall.
'A few years ago it was seen I was targeting (Loris) Karius,' Neville said in his Sky Sports analysis. 'Liverpool were being prevented from being a championship winning team from not having a goalkeeper. Lampard knows he will be sacked in the next two or three years if he doesn't win the league.

But just how does he compare to Kepa? And is he as good as Alisson and Ederson at Liverpool and City - the two clubs Lampard is in hot pursuit of?
Mendy only joined Rennes last year, joining from Reims but he helped the club reach third place in Ligue 1 last season. His stats across the course of that campaign, and one match so far this season, suggest he will be an upgrade on Kepa.
Mendy has played 34 times for Rennes in all competitions since joining in 2019 and in that same time span up to now, Kepa has clocked 42 appearances. And despite playing eight less games, Mendy has 12 clean sheets compared to Kepa's 10.
He also has a dramatically better goals conceded record - 32 goals have gone in against Mendy compared to 59 against Kepa.
