Arsenal boss Arsene Wenger was delighted with two-goal Alexis Sanchez in victory at Sunderland.
The Chile international made the most of horrendous errors by defender Wes Brown and goalkeeper Vito Mannone either side of half-time to secure a 2-0 victory for the Gunners at the Stadium of Light.
A delighted Wenger said: "He took advantage of the mistakes they made, but as well, he has super quality, Sanchez. He has quick feet and that's why he wins many balls that normal players don't win.
"In transition from offence to defence, he is very quick and wins the ball back very quickly, and you can take advantage of that."
