Pierce Morgan slammed Chelsea fans for chanting Abu's name, though he had previously expressed hope the Russian billionaire would buy Arsenal.
Pierce Morgan was caught on social media after seemingly changing his stance on Abu.
The Chelsea boss has said he intends to sell the club and in recent weeks he has found himself in the spotlight as he has been accused of having links to the club Vladimir Putin.
Russia invaded Ukraine to see the country's oligarchs collapse on fire Abu on Thursday to see his assets frozen by the British government.
Although he still retains the love of Chelsea fans, they have seen their club achieve great success because of his wealth.
They sang his name in the win burnley again over the weekend, in Thursday night's win over Norwich City.
Morgan took aim at the away fans, tweeting: "Are they also chanting Putin? #白痴.
Pierce Morgan tweeted in 2014 that he hoped Abu would buy Arsenal.
However, the broadcaster, who is an Arsenal in 2014, said he hoped the Russian billionaire would pour his fortune into the gunman.
Abu bought Chelsea in 2003 and the Blues have won five Premier League titles and other trophies since then.
Players and fans stood in Tevmore, Abu's chant open
Morgan previously tweeted: "I wish Abu had bought Arsenal 'Cash#Winner's#fans'.
His apparent big turn got this incredibly opinionated man to be shouted out on social media.
Blues boss Thomas Tucher admitted that the timing of the chanting of Abu's name was not appropriate given the support of the Ukrainians.
He said over the weekend: "Now is not the time to do this. If we show unity, we should show unity.
"We kneel down together and if the people at our club die, we show respect." Now is not the time to give additional information.
We also do it because we are a club. We show respect and we need our fans to commit to applause in this minute.
"We are doing this for the sake of the Ukrainian people, and there is no second opinion on the situation. They have our ideas and support and we should stand together as a club.
Chelsea have seen a series of sanctions against them, meaning they will not be able to consider any transfer or extend the contract of their current player.
Tickets will also not be sold for the game at Stamford Bridge, while the club shop has been closed immediately.
Captain César Azpilicueta told Premier League Productions "I have to admit that it was not a normal day. We can't control this.
"We came here, we focused on the game and we knew we had to fight for three points. We have to forget what's going on out there. ”
One netizen said: I'm pretty sure Morgan will only blush because he holds his breath, and his head is so far behind.
