Sadio Mané seems to have been denied what looked like a clear penalty on first glance.
Running into the box from the left, the Senegalese was tracked all the way by Gerard Piqué. The Catalan defender, with his arms flailing above him, seemed to nudge Mané to the ground from behind.
At root, it looked to be a foul on Mané as the Barça defender clipped him but it was light enough for the referee to wave it away.
Mané had the right to make the most of it by going down, but unfortunately it wasn’t given.
