Michael Essien believes Arsenal will be getting one of the best goalkeepers in the world if they sign Petr Cech from Chelsea.
The Ghanaian played alongside Cech at Stamford Bridge for eight years, so knows all about the Czech international's qualities.
Essien told ITV London's Will Mott: "Petr is one of the best goalkeepers in the world of football.
"I don't know about him moving to Arsenal, but that's football.
"Chelsea have Thibaut Courtois who is a good, young goalkeeper as well."
