Arsenal boss Arsene Wenger is delighted with the form of Aaron Ramsey.
The Welshman struck twice in victory at Sunderland.
"His intelligence, his desire to improve and [his] listening. He has a very learning attitude and he has a fantastic engine as well," said Wenger, who can see a clear improvement in the midfielder.
"Definitely, compared to one year ago. What he has achieved is fantastic."
