Who was United's Man of the Match?
Our no.1 justified his selection ahead of Andre Onana with some impressive saves - particularly in the second half, most notably from Martin Odegaard’s penalty, to help the 10-man Reds take the tie the distance.
In the shootout, Altay also made a stunning stop to deny Kai Havertz’s spot-kick, which was bound for the bottom corner - a save which proved decisive as United triumphed 5-3 on penalties.
According to Opta, Bayindir is the first Premier League goalkeeper on record, since 2013-14, to save a penalty in both normal time and in a penalty shootout in the same FA Cup game.
Talking to BBC Radio 5 Live afterwards, Ruben Amorim said of Bayindir: “Altay had a difficult game against Tottenham, but continued to do the same things in training, maybe without a smile, but he continued to work and today he is our hero.”
