Chelsea captain John Terry says goalkeeper Petr Cech will be a success at Arsenal.
According to reports, negotiations between the two clubs are progressing with the 33-year-old set to become Arsenal's first summer signing.
The Czech international lost his regular place after the arrival of Thibaut Courtois at Chelsea, playing only 16 games for the club last season.
"There's talk of Arsenal signing Petr Cech and, if they do get him, he will strengthen them for sure," Terry told the Alan Brazil Sports Breakfast show.
"He will save them 12 or 15 points a season.
"Petr was an unbelievable professional last year. When you get left out of the team it can be hard to accept but, when he came in [to the side], he was exceptional.
"He deserves a lot of credit for that. We understand he wants to play first-team football but nobody wants to see him leave the club.
"He's going to be sorely missed and will improve any side he goes to."
