"Sky Sports" report Barcelona's new sporting director said Lionel Messi could leave the club one day as Manchester City have the capital to fund such a move: "I believe it's very difficult that Messi will leave Barca but at times in football strange things happen. Now with these clubs that have so much money like (Manchester) City, certain amounts don't seem to have a value. In football things happen that appear impossible but I hope he will remain."
