Arsenal boss Arsene Wenger is delighted with the progress of Theo Walcott.

The England international made his 250th appearance for Arsenal in Saturday's 1-0 win at Sunderland, and earned special praise from his manager.

"It's unbelievable. I believe what this season shows is the remarkable evolution of Theo Walcott," Wenger told Arsenal Player.

"He's a complete player today and his transformation is absolutely sensational.

"He improves every week and it shows that he is remarkably intelligent as well, because he understands things quickly, takes them on board and is open-minded. That's why I believe he is always improving."
