The Arsenal fans in the Transfer Tavern aren’t feeling too confident about their upcoming clash with Chelsea…

In many ways, it’s a must-win game for the Gunners. A win against Bournemouth last week has done little to improve the mood of those in the pub, and a defeat against Chelsea will likely put them back to square one once more.

Still, there are reasons to be optimistic. Arsene Wenger, for all of his faults, has so much experience in the Premier League, and nobody is better placed to turn the season around.

What’s more, the bulk of the campaign is still left, and so perhaps a win against Chelsea could be the springboard the Gunners need to really improve their fortunes.

That’ll give them a lot of motivation ahead of the game, and it could play a big role in what would be a shock result if it were to come off.

Here are TWO reasons why Arsenal will shock Chelsea on Sunday – do you agree?

Alexis Sanchez

Alexis Sanchez has been in and around the Arsenal first team for the last few weeks, but he’s finally getting back to full fitness.

The Chilean picked up his form in Arsenal’s Europa League clash with FC Köln, and that could be a sign of things to come.

He is the ultimate big game player, and when Chelsea are the opposition, he’s sure to get even better.

Sanchez can be a game changer.

Derby Day

Everyone knows that when derby day comes around, form goes out the window.

Sure, Chelsea are on a decent run at the minute, but the pressure and intensity demanded by the Arsenal faithful could be just what is needed on the day to turn the game around. The Blues will be feeling good ahead of the game, but how far that will take them remains to be seen.

It’s one of the Premier League’s biggest rivalries, and nothing but a win will be accepted. That could be key.
