Petr Cech was performing better in training than Chelsea's other goalkeepers before Edouard Mendy's arrival, according to ex-Blues keeper Mark Schwarzer.
Cech, who retired in 2019, was a shock inclusion in Chelsea's 25-man Premier League squad when it was announced last week.
The 38-year-old was the fourth goalkeeper in the squad, joining Mendy, Kepa Arrizabalaga, and Willy Caballero.

Prior to Mendy's arrival from Rennes, though, Schwarzer said that Cech had been outperforming Kepa and Caballero in Blues training.
“From my understanding, he was better than the Chelsea keepers – but this was before Mendy arrived at the club," Schwarzer told Optus Sport.
