Watford striker Josh King has admitted playing frustrations this season.

King scored a hat-trick in last night's 9-0 friendly win against Armenia.

"It has been frustrating. I have not understood why I have not started until now. There are many good players, but I have been surprised," says King.

This was the first start for King under Norway coach Stale Solbakken.

"I understand that Ståle has a tough job of choosing the XI who will start. We have a lot of good players. I mean I should start, but he has disagreed. I respect that. I've been disappointed, because I've been stuck for almost eight years, but I've been waiting for my chance. I think I delivered a good performance, with three goals and one goal-scorer."
