Manchester United stewards were forced to wrestle a pitch invader to the ground after a supporter raced on to the pitch and tugged on Cristiano Ronaldo's shirt.
Ronaldo's heroics once again helped United to a stunning comeback victory in the Champions League, after he scored a crashing header late on to seal the result.
The superstar was unable to hide his delight at full-time, having dropped to his knees and roared with sheer emotion before making his way towards the tunnel.
It was here, however, that one fan clearly caught up in the thick of the moment made the mistake of storming the surface and heading in the direction of Ronaldo.
