His short career has so far been blighted by disciplinary problems but Suffo has undoubted talent.
While at Nantes in France he was banned for eight months for clashing with a referee.
And he has been told he has no future with Sheffield United after his part in a mass brawl during the First Division game against West Brom in March.
Suffo was packed off to Spanish Second Division side Numancia on loan for the remainder of the season.
A powerful forward who is dangerous when running at defenders, he needs to perform well this summer to help his search for another club.
