Watch Sanchez's vital first goal for Arsenal

Alexis Sanchez put Arsenal ahead in their crucial Champions League play-off second leg match with his first goal for the club.

The Chilean started at centre-forward for the Gunners and just before half-time finished off a quick move between Jack Wilshere and Mesut Ozil.
The ex-Barcelona player, who signed for £35m earlier this summer, saw his shot squeeze under goalkeeper Tolga Zengin.
If this goal proves enough to qualify for the group stage, it could be worth at least £25m to the club – not a bad way to start paying back his transfer fee.
