Gunners legend: Arsenal star is key to Arsene Wenger's success

Arsene Wenger is "such a key player for Arsenal," according to former Gunner Ray Parlour.

The Chilean has scored five goals in eight appearances this season as Arsenal sit second in the Premier League table.

Sanchez scored a memorable hat-trick in their 5-2 victory over Leicester last month and grabbed a brace in Arsenal's 3-0 demolition of Manchester United before the international break.

But the 26-year-old didn't stop there. Sanchez scored in Chile's 2-0 victory over Brazil and added another two strikes in their 4-3 victory against Peru in their World Cup 2018 qualifiers.

And Parlour - who made 339 league appearances for the Gunners - believes the best is yet to come from the winger.

"He is in great scoring form at the moment, with his hat-trick against Leicester and the goals against Manchester United, and he's carried that on (for Chile)," he told Sky Sports.

"He's such a key player for Arsenal, the way he plays with his energy and the goals he's scoring from the left-hand side. He's huge for them.

"He had a slow start, but he's really improved in the last few weeks and he'll want to play every game."
