The Gunners had drawn their previous two games but Sanchez settled the nerves with a neat finish on the turn from outside the area.

West Brom's Gareth McAuley hit the bar with a header but that was as close as they came to a goal.

And Sanchez's driven free-kick secured the win for Arsenal, who move up to third, five points behind Tottenham.
