Tottenham boss Ange Postecoglou admits he was frustrated with Yves Bissouma's red card in victory at Nottingham Forest.
The midfielder saw red after Spurs struck twice for their 2-0 win on Friday.
Postecoglou later said: "It's an issue but it's not so much discipline.
"I haven't seen a slowed down version but it's just a desperate lunge more than anything malicious. The guys are having to adapt to learn to play our football without crossing a line but I loved the commitment they showed.
"Unfortunately we paid a price because it's not just this game, he obviously misses a big chunk of football but it is what it is."
Asked his view on the decision, Postecoglou added: "I think they slowed [the tackle] down [on replay] and they saw what they saw, and we have to cop it."
