Chelsea have signed Rennes goalkeeper Edouard Mendy for £22m on a five-year deal.

The 28-year-old is Chelsea’s seventh first-team signing of the summer following the arrivals of Hakim Ziyech, Timo Werner, Ben Chilwell, Thiago Silva, Malang Sarr and Kai Havertz.

Mendy will compete with Kepa Arrizabalaga and Willy Caballero to be the club’s No 1.

Mendy said: “I am so excited to be joining Chelsea. It’s a dream for me to be a part of this exciting squad and to work with Frank Lampard and all of his coaching staff. I look forward to meeting my team-mates and can’t wait to get started.”

The Senegalese follows the footsteps of Petr Cech – now Chelsea’s technical and performance adviser – who made the same move from Rennes to Stamford Bridge in the summer of 2004.

Mendy kept nine clean sheets in 24 Ligue 1 appearances last season with Rennes, helping them to finish third and qualify for the Champions League for the first time in club’s history.
