He has made 82 league appearances for Valencia, having spent two years in their youth teams. Guerra has only missed four La Liga games in the past two seasons, making him a valuable asset for any team. Manchester United is believed to be keen on signing him, with some reports suggesting they have a long-term contract agreement in place.

Guerra's decision to turn down a new contract offer from Valencia has fueled speculation about his future. Manchester United's manager, Ruben Amorim, is said to be in need of a player who can control the middle of the pitch. Guerra is reportedly available for around £20 million, but Valencia's loss of midfielder Christian Mosquera to Arsenal may make it harder for Manchester United to sign him this summer.
