Ex-Manchester United, Manchester City and Juventus striker Carlos Tevez gave away the winning penalty on Saturday as Boca Juniors faced rivals River Plate in the least friendly "friendly" match you'll see for some time.
In total, there were five red cards (three to Boca, two to River Plate) and a further nine yellows, according to the Guardian.
River Plate's goalscorer Leonardo Pisculichi and Jonathan Maidana were dismissed for their involvement in a scuffle that broke out when the latter headbutted Tevez.
Earlier, Boca's Jonathan Silva (on debut), Gino Peruzzi and Daniel Diaz were all shown red, to go with the side's two dismissals in their midweek defeat to Racing Club in Mar del Plata.
In all, referee Patricio Loustau awarded 40 free-kicks throughout the match.
"Neither of us behaved well," said Tevez after the match, putting forth his contender for understatement of 2016.
