The Spain defender had a successful wrist operation after he was hit by flying glass caused by three explosions that shattered the windows of the vehicle as the team began their trip to the Westfalenstadion ahead of the Champions League quarter-final first leg against Monaco.
And he has allayed any further fears over his injuries by posting a picture of him smiling on Instagram with his right arm in a cast.
In his message he writes: "Hello everybody! As you can see I am doing much better.
"Thank you everybody for all your support and your messages! All my strength to my team mates, supporters and fans and to BVB for tonight's match! #HejaBVB."
