Chelsea goalkeeper Thibaut Courtois has welcomed the arrival of former RacingGenk teammate Kevin de Bruyne.
Courtois is currently on-loan with Atletico Madrid.
"He will learn a lot and grow at Chelsea," said Courtois. "I think the move is ideal, especially as he'll spend the first six months back at Genk.
"His potential is enormous, I know he is good enough. Three Belgians (including Romelu Lukaku) at Chelsea. Is this not great for our football? I hope in a couple of seasons we're all playing for the Chelsea first team."
