Pep Guardiola refused to comment on Kyle Walker's red card after Manchester City's 1-1 draw against Everton on Monday Night Football.
The £50m summer signing from Tottenham was dismissed by referee Bobby Madley for two yellow cards in quick succession before half-time.
His first came after a late challenge on Leighton Baines but Guardiola was particularly upset by Walker's second booking, awarded after a collision with Dominic Calvert-Lewin.

The City boss was seen deep in conversation with fourth official Michael Oliver at half-time but when asked by Sky Sports for his view on the decision, Guardiola said: "Next question please. I want to be at Bournemouth."
City, who face Bournemouth on Sky Sports Premier League on Saturday, missed several presentable opportunities before falling behind to Wayne Rooney's first-half strike
They battled back despite their numerical disadvantage to equalise through Raheem Sterling before Everton midfielder Morgan Schneiderlin was also sent off late on in a fiery encounter.
Guardiola was pleased with the performance, saying "it is one of the proudest days of my life", but he admitted City need to be more clinical in the final third.
"We played a good performance. In the second half we made a good performance, similar to last season when we played them here," he added.
"We created chances but we didn't finish it. We have to try to create those chances."
Sterling was introduced at half-time for Gabriel Jesus and City improved in the second half.
On the substitution, Guardiola said: "At half-time we changed. During the second half we created more chances. We brought more players into the middle for more control and we created enough chances.
"We are here for the results so at the end we have to try to analyse the performance but it is one of the most proudest days of my life seeing how we have done.
"Ten against 11 for Everton, a Europa League team, top quality of the players. It is not easy and we tried. We missed at the end some chances. When we didn't score goals in that way we could not win."
