Fred has appeared to suggest the referee was wrong to send him off in Man United's defeat by Paris Saint-Germain in the Champions League.
The midfielder was given his marching orders in the 70th minute after a string of late tackles and a first-half clash with Leandro Paredes.
Fred was arguably fortunate to avoid a red card after headbutting Paredes and many expected United boss Ole Gunnar Solskjaer would substitute him at half-time.
But astonishingly the 27-year-old emerged from the tunnel after the interval, only to be sent off for a late tackle on Ander Herrera just one minute after PSG restored their lead at Old Trafford.
Replays showed Fred won the ball first and, despite his array of yellow or red card-able offences throughout the match, the Brazilian appears to disagree with his sending off.
While he doesn't verbally comment on the tackle that lead to the booking, he took to social media to post an angle of the incident showing he made contact with the ball first.
Accompanying the post on his Instagram page, he wrote: "It wasn't the best night, but we kept working for the best. Always strong mind. We are United! #MUFC".
"Fred has played really well. We spoke about staying calm and on your feet [at half-time]," said the Red Devils boss.
“The second yellow card was nowhere near a foul. Ander knows that. Fred shouldn’t put his head towards Paredes [but] I don’t think he touched him. He was a bit lucky to stay on."
As 10-man United pushed for an equaliser, PSG punished them on the counter-attack as Neymar grabbed his second of the night in added-time.
The French giants' 3-1 win leaves Group H in the balance, with PSG, United and RB Leipzig all on nine points.
The Red Devils must avoid defeat away to Leipzig next week to secure qualification to the last 16.
Did Fred deserve a second yellow card for his challenge on Ander Herrera? Have your say here.
