The ball bounced up in the air and the Brazilian defender raised his foot which caught Fellaini in the knee. David Luiz received a yellow card for the challenge, but Souness feels that the Chelsea man should have been given a red card.
"That's not a difficult decision to make," Souness said while working as a pundit for 'Sky Sports'. "The referee has a full view of it. Does he not see six studs showing? He's seen something so he gives him a yellow card.
"By the shape of David Luiz going for the ball that is extremely high. It's a red card.
"Martin Atkinson has completely bottled it".
Jose Mourinho refused to comment on the incident after the match.
