When Cesc Fabregas left the field in the game against Southampton, Chelsea fans let the Spanish player know how they felt about his performance. He probably did not like it, but Jose Mourinho Jr. used Instagram to criticize fans.

The son of Chelsea’s coach currently plays for a youth team in Fullham’s academy. He does still manage to stay close to what happens with his dad’s team. On Sunday, he just couldn’t hide the way he felt about the fans reactions.

“Why is everyone hating and blaming Fabregas for Sunday's performance… It was a team effort,” Mourinho Jr. said on the social media site. “ I've seen bad Chelsea fans but Sunday was the worse I've ever seen.”

The 15-year-old boy did not hold back on his words

He did recognize Chelsea was not playing the way many people expect. He also was eager to point out that Fabregas had a bad day on Sunday. Finally, he also mentioned how Fabregas has shown some heart throughout the game.

The post ended by siding with his dad. His last words were probably the ones that hurt fans the most.

"Mourinho's right, you're fans are s---e" Our fans are a disgrace!!!!” your Mourinho said.
