He hasn't featured in a single minute of competitive action for Barcelona, since moving from Arsenal last summer, but Thomas Vermaelen is still proving a lucrative piece of transfer business - at least, as far as The Gunners are concerned.
On top of the £15 million cash received by Arsenal last summer, Barcelona also agreed to further structured bonus payments, as part of the deal, per a report by the Telegraph.
If Barcelona beat Juventus in the Champions League final, an additional bonus payment of £3million will be due to Arsenal, who clearly drove a hard bargain, mindful of the potential success the player could enjoy with the Catalan giants.
Vermaelen has effectively missed out on an entire season of action, due to a troublesome recurring hamstring problem, which eventually required surgery.
After going under the knife at a specialist clinic in Finland, the Belgian defender began the lengthy process of recovery, finally joined group training with the rest of the Barcelona squad, at the very end of March.
Since then, the 29-year-old has featured in squad calls ahead of matches, which made him available from the bench, but has yet to make his official first-team début.
The only semi-competitive action the former Arsenal captain has seen, whilst donning the famous blaugrana shirt of Barcelona, was for the B team in a friendly against Indonesia U19's, back in September 2014.
Whilst he's now fully fit, the strong form of defenders such as Pique, Mascherano and Mathieu, has meant Vermaelen has needed to remain patient, though he is expected to get some minutes, during the final two La Liga matches.
