Watford boss Walter Mazzarri says Isaac Success' call up to the Nigeria squad is well deserved.

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

Mazzarri 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."
