Barcelona want Chelsea keeper Thibaut Courtois to be their new number one next season and have made enquiries about his availability. Sportsmail understands they have placed him above Borussia Moenchengladbach’s highly-rated Marc-Andre ter Stegen on their wish list to replace Victor Valdes and have sounded out aides over whether he would welcome a move to the Nou Camp.
