Swansea City midfielder Jonathan de Guzman is backing Holland teammate Robin van Persie to end his drought for Manchester United.
United's £22million striker scored an injury-time winner at the Etihad Stadium last December to clinch a crucial 3-2 win - which sent Sir Alex Ferguson's men on their way to reclaiming the Premier League title.
De Guzman said: "I'm confident Robin will deliver against Manchester City.
"He's been delivering all season and he's a world-class player."
