Walter Mazzarri believes Isaac Success has a big future for club and country after the striker received his first call-up to the full Nigeria squad.

The 20-year-old could feature for Nigeria in their World Cup qualifier against Zambia next month.

Success has made an impact for Watford off the bench in recent games and Mazzarri has high hopes for the powerful forward.

The Hornets head coach said: “We’re very pleased for him. We think we helped for him to get a call-up from the national team.

"He’s a very young player and if he follows our mentality at this club we think he’s going to have a very good future with this team and for his national team.”

Success is still waiting for his first competitive start for the club and is set to be on the bench again at Burnley on Monday.
