He had it on for 20 minutes after Lionel Messi went off at half-time
One of the more curious sights during Barcelona's 3-0 win over Boca Juniors in the Joan Gamper Trophy was seeing goalkeeper Jasper Cillessen with the captain's armband.
The stopper came on for Marc-Andre ter Stegen at half-time and took the armband after Lionel Messi went off. However with Sergio Busquets coming on in the 64th minute it was shortlived as the defensive midfielder took over.
It's not the first time that Cillessen has worn the armband - he had it during the ICC game against Tottenham.
