Canos transferred to Brentford in 2017, for whom he had previously played on loan from Liverpool during the 2015–16 season. He's made over 200 appearances for Brentford, but has struggled for playing time this season and with his contract running out this summer he could be on his way out. He's scored over 30 goals for Brentford and has played various positions from central midfielder to attacker.
He is 25 years of age and has a lot more playing time in him, he is at that age where his prime is just beginning, so maybe he could return to form at Valencia CF. He is a versatile player and can cover multiple positions.
