Boca Juniors brought their Superclasico rivalry with River Plate to a whole new level on Thursday night.
It was the third time in 12 days the two clubs have played each other, with the latest clash deciding who would progress in the Copa Libertadores.
River arrived at La Bombonera with a 1-0 lead from the first leg and must have prepared themselves for trouble.
A drone with a ghost marked ‘B’ was flown over the players before kick-off – taunting them about their relegation in 2011 – before the game eventually got going.
However, with the match still scoreless at half-time, River’s players were pepper-sprayed as they returned to the pitch.

The game was suspended with riot police forming a protective tunnel to get the players off the pitch.
