Dani Alves was replaced after 75 minutes during Barca's 2-1 win against Man City tonight. He had just been involved in a clash with Gael Clichy which saw the Man City defender receive a second yellow card.
The Brazilian received medical attention after the challenge but what happened after that probably hurt even more than the actual tackle from the French player.
Alves made his way towards the bench, kicked a water bottle and in the process smacked his knee off the railing.
