Gianfranco Zola believes there is still much more to come from Fernando Forestieri despite the Watford forward creating one and scoring the other in his side's 2-1 win over Leicester City.
Forestieri was tipped for great things in his teens when he broke into the Genoa side at the age of just 17 but he has struggled to live up to the hype in recent years and, now 22, joined Watford on loan from Udinese in the summer.
Watford head coach Zola said: "He is a young player who has got a lot of potential but he needs to learn to use this potential. Sometimes he doesn't but we are here to help him and I am sure he will become better and better. I feel there is a lot more to come from him."
Watford took the lead when Forestieri's neat flick released Almen Abdi and he calmly slotted the ball past Kasper Schmeichel after 14 minutes. That lead was doubled in the second half when Schmeichel could only parry Daniel Pudil's volley and Forestieri tapped in from close range.
David Nugent pulled one back soon after but Leicester's hopes of a point suffered a blow when Zak Whitbread was sent off for a second yellow card on 83 minutes and the Hornets held on with ease.
Zola said: "It was very good to win against a really strong side who are one of the best teams we have played against. They made it very difficult for us but there were times in the game where we played very well."
Leicester had a few penalty appeals in the second half but City boss Nigel Pearson refused to hide behind refereeing decisions.
He said: "I have seen them again and whilst I have seen them given, I do not want to use them to mask the fact that we have not played as well as we could have played. That is two games running which is something we need to rectify relatively quickly.
"But what I would say is as a group of players, so far this season they have been excellent.
"On the face of it, yes it has been a tough couple of games where we have not performed well as a team. But the reason for this is because we have too many players who are not quite hitting the very high standards of performance that they have hit so far this season."
