Swansea City midfielder Jonathan de Guzman is confident that his Netherlands international teammate Robin van Persie will end his goalscoring drought in the Manchester derby.
The Manchester United striker hasn't found the target at club level since February, a run that has lasted nine games in all competitions.
However, Van Persie did score three times in the Netherlands' two recent World Cup qualifying games.
De Guzman told reporters: "I'm confident Robin will deliver against Manchester City. He's been delivering all season and he's a world-class player."
Van Persie has scored 19 goals in the Premier League this season.
