(REUTERS) Alexis Sanchez scored twice as Arsenal easily beat 10-man Hull City on Saturday (Sept 17), securing a third successive Premier League win for the first time since January.

Sanchez put Arsenal ahead after 17 minutes, deflecting the ball home after a Theo Walcott shot was pushed into the path of Alex Iwobi, before the hosts had Jake Livermore sent off for handball.

Sanchez's penalty was saved by Eldin Jakupovic, but Walcott doubled the lead 10 minutes into the second half when his effort was headed in by Hull defender Harry Maguire.

Hull's Robert Snodgrass pulled a goal back from the penalty spot, but Sanchez calmed any jitters in the Arsenal ranks when he rifled high into the net and Granit Xhaka rounded off the scoring with bullet finish from distance in stoppage time.
