Arsenal won their first Premier League match in over one month on Saturday as Arsene Wenger's side out-gunned a defensively woeful Sunderland at the Stadium of Light.
Maximum points may not have been banked had it not been for the work-rate and ball-winning ability of Alexis Sanchez, as the Chilean's characteristic tirelessness yielded him a brace of goals.
It was the 25-year-old's fifth goal of the season in the league, one which he has also contributed two assists and 18 key passes from just seven starts (and one substitute appearance).
His reliability on a week by week basis has earned Sanchez praise from a former Manchester United striker Dwight Yorke, now a pundit for Sky Sports.
"Arsenal and everyone who has watched world football saw what he was doing at Barcelona before he joined the club," he said. "He had a terrific World Cup and he's come to Arsenal with a lot of expectation, a lot of money has been paid for him and he's delivering.
"He's delivering week in week out," Yorke noted. "He's really risen the occasion and he's come in to a new environment and he’s quickly adapted to being an Arsenal player.
"He's been outstanding. He's that type of player with his fantastic skill and ability to play for the team, but he's also getting in on the goals and that's eight so far this season [in all competitions].
"That's a terrific return."
