Barcelona coach Tito Valanova has stepped down according to reports in Spain after it was reveled that he suffered a tumor relapse.
The 44 year former player had a tumour removed last November from his parotid gland while working as the Catalan club's assistant coach.
The operation was viewed as a success, and Vilanova returned to work with Barca, eventually taking over from Pep Guardiola when he stepped down from his post in April.
Spanish television station Cuatro reported that Vilanova had suffered a relapse and had decided to step down with immediate effect.
The club's regular Wednesday press conference was cancelled this morning in light of what has happened.
Barcelona have already contacted their first-choice candidate to replace him on a temporary basis for the remainder of the season and are awaiting a decision.
