Barcelona are about to sign Thomas Vermaelen after agreeing a £15 million deal with Arsenal, according to the BBC.
The defender was the subject of bids from both Barcelona and Manchester United but the latter pulled out of the deal earlier today after negotiations broke down with Arsenal.
Arsenal apparently wanted Chris Smalling as well as cash from United but this was refused and the deal broke down.
Now Vermaelen has to agree personal terms and pass a medical with Barcelona.
The Belgian defender joined Arsenal in 2009 in a £10m transfer from Ajax, going on to to make 150 appearances and score 15 goals.
