Arsenal head into the weekend's action knowing they need three points to keep pace with the teams around them vying for the Premier League title and UEFA Champions League qualifying positions.An impressive win against Swansea last week gave them a much needed confidence boost and the visit of Burnley offers the chance for them to pick up another big win.The Gunners have scored at least two goals against Burnley in the Clarets' last four visits to the Emirates Stadium.Their last Premier League encounter against Burnley at home ended in a 3-1 win for the North London side, part in thanks to a double from Alexis Sanchez.The Chilean forward will be vital again on Saturday if Wenger's side are to get a result with his deadly goalscoring keeping Arsenal on the up and up this term.Sanches has scored 16 goals for the Gunners this season including 14 in the Premier League. However, it's not just his finishing ability catching the eye. This stat from Opta shows just what an incredible creative force his is too.No player has created more chances in Europe's top 5 leagues from open play than him.

It's an incredible statistic when you consider how many goals he's also contributing. With less than 18 months left on his contract at the Emirates, Wenger and the club would do well to get him signed up as quickly as possible or risk losing not just a lethal goalscorer but also a massive creative force.
