"It will be fantastic if he joins Atletico in January," Alderweireld told Het Laatste Nieuws.
"Kevin is an excellent player. He knows how to play football.
"On the other hand, this team is already shaped and is doing well in the league.
"If he decides to leave Chelsea, he has to move to a team where he can play regularly, because the World Cup is coming."
