He told the Official Web-Site: "It was very disappointing to miss the game with Sunderland and it was very frustrating to watch from the stands.
"But I'm focussed on hopefully returning for the Watford game.
"I always seem to manage to score at Vicarage Road, and remember the two I scored last season, and hopefully I can get my goalscoring back on track there."
He added: "Just goal difference seperates the two teams in the league so it should be a close game but I see no reason why we can't come away with three points."
