Not entirely sure who won this mini Twitter argument.
Usually, when two teams are getting ready to play each in other in one of their biggest games of the season, you would imagine they would be psyching themselves up.
And with Arsenal facing off against Spanish giants and La Liga leaders Barcelona, you'd guess that they would be doing everything to get one over their rivals.
However, Barca decided to get the first blow in by being very cheeky with the Gunners on Twitter; just have a look at the backwards and forwards these two had:
Not a bad start, but Arsenal well and truly hit back with a video of one of Henry's most famous goals and probably his best celebration ever:

But Barca hit back with this stunner:
This is all a bit too nice, isn't it?! We reckon Barca are trying to lure Arsenal and their fans in before unleashing Lionel Messi, Luis Suarez and Neymar on them in the first leg of their Champions League clash at the Emirates.
The last time these two sides met in North London resulted in a shock 2-1 win, with goals from Robin Van Persie and Andrei Arshavin.
Can Arsenal pick up another surprise win over the Spanish giants?
