Defender Samuel Umtiti has claimed that he is 'concerned' that his release clause at Barcelona is "not that high".
Since leaving Lyon for Camp Nou in July 2016, Umtiti has established himself in the centre of the Spanish side's defence, but the French international is currently available for £52m due to the terms of his contract.
Manchester United and Manchester City are both allegedly keen on Umtiti, and although the 24-year-old says that he is "very happy" at the La Liga giants, the player has suggested that he has worries over his future.
Umtiti is quoted by The Express as saying: "My clause isn't that high, everyone knows it. It's something that concerns me, but I don't particularly care about it right now.
"However, everything happens very quickly in the world we live in. All I can say is that I'm very happy here. My renewal? This is a subject that I don't want to discuss too much. For my part, nothing's started."
Umtiti still has over three years left on his existing contract.
