Manchester City were at their imperious best in their Carabao Cup semi-final first leg against Burton Albion.
Pep Guardiola sent out a strong team and they would go on to make light work of the League One outfit.
Kevin de Bruyne got the scoring going in the 5th minute and City would never look back, scoring eight more times over the course of the night.
Gabriel Jesus bagged four goals on the night, while Phil Foden, Oleksandr Zinchenko, Kyle Walker and Riyad Mahrez all got their names on the scoresheet.
However, despite the romp, it wasn't all good news for Manchester City fans.
De Bruyne has been injured for much of the season but was given a start against Burton.
The 27-year-old looked back to his best as he opened the scoring.
But, after being taken off in the 58th minute, the Belgian midfielder left the field with his head down and walked straight down the tunnel.
City fans have been concerned by De Bruyne's actions, feeling he has perhaps suffered a reoccurrence of an injury.
It is also customary for players to watch the rest of the game unless they are injured.
The Times have now revealed exactly why he walked down the tunnel and it comes as good news to City fans.
Quite simply, De Bruyne left the pitch because he was unhappy about taken off.
They understand that the Belgian was not injured, and instead was angry with Guardiola for substituting him.
Given it was just his fourth start of the season, De Bruyne wanted more game time to work on his fitness.
Thus, that prompted him to leave the field in anger.
Paul Hirst, the journalist who wrote the article, then followed it up with a tweet.
It seems that City fans have nothing to worry about.
In fact, upon hearing the news, many City fans are actually praising De Bruyne's mentality.
The report goes on to state that the Belgian midfielder is likely to start against Wolves on Monday, which will be just his second start of the season.
