The agent of AS Roma striker Seydou Doumbia is confident he'll silence his doubters.

Doumbia struck in victory over Sassuolo this week.

Agent Jean Bertrand Beytrison told Calciomercato.it: "I just say that at times in football there is no middle ground, so people either think you're a 1 or a 10.

"Future? Let's not joke around, we've only been here a few months. We are exclusively concentrated on the field to conclude this season in the best way."
