It remains one of life's mysteries how Marcos Rojo was never sent off playing for Manchester United.
The tough tackling Argentine defender was no stranger to picking up yellow cards for United, yet he just somehow managed to escape seeing red during his seven-year stint at Old Trafford.
However, Rojo was shown a straight red card during Boca Juniors' 1-0 win over River Plate on Sunday. With the game heading towards its conclusion, Rojo decided to fly into a challenge with his left boot high, and he ended up catching Matias Suarez on the head, leaving the referee no choice but to send him off.
