Jose Mourinho's teenage son has launched a stunning attack on Chelsea fans, labelling them a "disgrace" after they booed Cesc Fabregas in the 1-1 draw against Southampton on Sunday afternoon.
The aptly-named Jose Mourinho Jr, a promising young goalkeeper who was reportedly taken on by Fulham in May 2014, took to Instagram to pan the Blues' faithful.
Interestingly the account was taken offline on Monday afternoon - shortly after news began to spread that Mourinho Jr. had published the controversial post - but screenshots are still doing the rounds on social media.
Mourinho Jr: Chelsea fans are a disgrace
Posting a picture of Fabregas, Mourinho Jr. wrote for the caption: "Sunday's performance… It was a team effort. Fabregas might not have played as well as most expected but at least he kept fighting… Showed a lot of character, I've seen bad Chelsea fans but Sunday was the worst I've ever seen."
"Fans booing Cesc not singing at all, I completely agree with the chant "Mourinho's right, you're fans are sh*te," he added. "Our fans are a disgrace!!!"
Mourinho now in a difficult position
One suspects Mourinho Jr. might find himself a spot of bother with his famous father once he discovers the content of his son's latest Instagram post.
Mourinho has an excellent relationship with the Chelsea fans, but this incident may put the revered Portuguese coach in a difficult situation.
It's important to remember Mourinho's son is still very young - and whereas most kids his age can post their thoughts on football without fear of any repercussions, it's different for the child of such a famous figure.
Mourinho Jr was right to slam Chelsea fans
However it could be argued that Chelsea fans who took it upon themselves to boo Fabregas - one of their most outstanding performers over the season as a whole - deserve criticism.
Chelsea might have suffered a shock Champions League elimination at the hands of Paris Saint-Germain last week, but they remain on course to win the Premier League title and have already secured the Capital One Cup after beating Tottenham earlier this month.
Fabregas, who joined Chelsea from Barcelona last summer, has struggled to produce his best form since January but was fantastic during the first half of the season.
In 24 Premier League appearances, the Spain international has scored two goals and contributed 15 assists.
While it's easy to understand why Chelsea fans were frustrated on Sunday - Manchester City's defeat to Burnley on Saturday handed the Blues an excellent chance to leave themselves with one hand on the Premier League trophy - booing Fabregas is inexcusable.
Some fans might argue they have paid good money to be at Stamford Bridge and are subsequently entitled to do what they please - but booing players is always, without exception, counter-productive.
Getting behind their team and players, including Fabregas, might have led to a very different outcome.
