|19/2||Adnan Januzaj is 19/2 with BetVictor to score the first goal in Real Sociedad v Man Utd|
"For me, it was a red card for the right-back," the Belgian told MUTV. "I hope the referee looks at the video later."
David Moyes, meanwhile, has indicated that Januzaj is likely to be involved when the Red Devils face Real Sociedad in the Champions League, having previously been an unused substitute against the Basque side at Old Trafford.
"He's definitely ready to play [Champions League football]," Moyes enthused. "He's not got a problem. We're trying to bring the boy along at the right pace if we can.
"He's not tired and we've not seen any dips in form just now so I'm sure we'll continue using him and he'll definitely be in and around the squad."
