The north London side have had to face plenty of criticism in recent days in the wake of their back to back defeats by Barcelona and Manchester United.
Their 3-2 loss at Old Trafford on Sunday left Arsenal six points behind leaders Leicester heading into their game against the Swans on Wednesday night at The Emirates.
Arsenal are aiming to win their first Premier League title since 2004 this season and can move to within three points of top spot by beating the Swans on Wednesday.
And Costa Rica international Campbell was staying positive in the build-up to the game in north London.
Campbell tweeted on Tuesday:
@joel_campbell12 We can still win the league this year & the FA cup as well…COME ON YOU GUNNERS!!
