Thursday's Manchester derby was fairly unspectacular when it came to goals, but Marouane Fellaini's headbutt of Sergio Aguero has at least provided a talking point from the clash.
In a match that failed to live up to the hype, a dominant City were unable to find a way past a resolute Red Devils, who played the final minutes with 10 men due to Fellaini's straight red card.
The Belgian was given his marching orders for an apparent headbutt on Aguero, which took place just 19 seconds after the United midfielder had picked up a yellow card.
As Fellaini eventually trudged off the pitch, he was seen having a brief conversation with his manager, and with the help of video replays and a few lip reading experts, it seems that Mourinho had very little idea what was happening.
According to all manner of amateur lip-readers on social media (and the eyes of anyone who's watched the clip), the Portuguese allegedly asked his player: "Wait, what happened?", before Fellaini sheepishly replied: "I don't know".
Despite appearing to have very few understanding of the incident at the time, Mourinho was scathing of Aguero's role in the red card when speaking after the game, as he labelled the forward a 'smart Argentinian player'.
Jose: "Wait! What happened?"
Fellaini: "I don't know"

Speaking to the Irish Independent, he said: "Marouane says it was a red card because he is Marouane, Martin Atkinson told me in his opinion it was a red card but I saw Aguero in the tunnel - no broken nose, no broken head, his face is as nice as always."
United have yet to confirm whether they will appeal the automatic three-match suspension that has subsequently been handed to Fellaini, but considering replays showing a clear attempt at violent conduct, the Red Devils will likely accept the punishment and hope that the FA don't extend the ban further.
