Stefan Savic has always been an enigma - and Wednesday night showed the Atletico Madrid defender's dark side in all of its shame.
On the pitch, with the ball in the play, the 31-year-old Montenegrin was a colossus as Atletico nullified Manchester City with relative ease. He didn't commit a single foul over the two legs and was tidy in possession.
Yet we saw the worst of him in the shameful scenes that marred the end of the gripping Champions League quarter-final.
After Phil Foden was kicked by Savic's central defensive partner Felipe in the 90th-minute, earning the Brazilian a second yellow, the young England star rolled back on to the pitch to try and kill time - but Savic was having none of it.
