The 22-year-old Newcastle forward took to social media with a determined outlook.
The Frenchman feels Newcastle's loss is 'difficult' to accept and has thanked supporters for making the trip to London.
Thauvin came on in the second half against the Gunners.
Difficult to take this defeat. The team will not give up, we will keep fighting. Thank you to the fans for having made the trip to London !— Florian Thauvin (@FlorianThauvin) January 2, 2016
On this occasion, there appears to be a lot less criticism aimed at the Newcastle United squad. Against top teams, they always seem to turn up - so there wasn't the level of mediocrity they have often shown this season.
And the level of Newcastle's performance against Arsenal was better than anyone could have hoped for. It was simply a case of taking their chances - but that's nothing new for the Magpies.
Will the club strengthen in the final third in January? Not signing a clinical finisher - as they did in summer - could cost them their Premier League status.
With displays like the one against Arsenal, though, there is certainly hope Newcastle can get the job done in terms of staying up. But they need to deliver every week, finishing off some of those chances while they're at it...
