Arsenal have missed out on a £2.9 million payment from Barcelona after a clause in the deal that took Thomas Vermaelen to the Nou Camp was voided, reports The Evening Standard.
It has previously been reported that Barcelona would have to pay the fee to Arsenal if and when they won this season's Champions League.
Having seen off Juventus in Berlin on Saturday night to claim their fourth European title in nine years, Arsene Wenger was surely looking forward to getting a little extra added to his summer transfer budget.
However, Barcelona owe nothing on the £15m deal because Vermaelen failed to play a single minute of this season's Champions League.
Nou Camp officials entered into the contract that should Vermaelen fail to make an appearance in the competition then the £2.9m clause would be void whether Barcelona win it or not.
While the money will surely be missed by the Gunners, they can reassure themselves that they got the better end of the deal when they sent their captain to La Liga.
Vermaelen spent the entire season getting to know the Barcelona medical team, suffering a series of hamstring injuries and only managed to make his debut in their final home game against Deportivo.
He wasn't need, of course, as Leo Messi, Neymar and Luis Suarez inspired Barcelona to an incredible treble-winning season.
Well replaced at Arsenal
Not only that, but Arsenal have also been fine without the Belgium international with Wenger using the money generated from his sale to purchase Southampton starlet Calum Chambers.
The youngster went straight into the first-team to cover for an injury crisis and certainly impressed, earning a call-up to the senior England squad as a result.
Fighting for his career
Now Vermaelen faces a fight to save his Barcelona career and he will be hoping that their transfer ban will play into his hands.
Barcelona can't sign any new players until January and, if Vermaelen can stay fit, he will have six months to prove he can stay fit and play in Barcelona's starting XI.
Has Vermaelen got what it takes to make it at Barcelona or should he be sold as soon as possible?
