Arsenal manager Arsene Wenger has hailed Aaron Ramsey after the midfielder scored twice in the second half to give his side a 3-1 victory at Sunderland.
The Welshman has featured in each of Arsenal's four Premier League games so far, and Wenger believes that this is a testament to his hard work.
"He works very hard and has improved dramatically," he told reporters. "It's absolutely fantastic what he is doing. He is a different player to one year ago in September. Many people questioned him, so credit to him."
The result lifts Arsenal to the top of the Premier League.
