The club record signing was destroyed by fans for his awful miss in the Community Shield clash yesterday (August 6).
And Batshuayi – whose game time may be reduced with the arrival of Morata – couldn’t hide his emotions.
A short clip going viral on Twitter shows the Belgian standing behind the £75m signing.
He then breaks into a huge grin before seemingly spotting himself on camera and turning serious again.
Fans were quick to comment on what they thought the 23-year-old was laughing at – with many coming to the same conclusion.
“Batshuayi laughing at Morata after he missed his penalty,” one wrote.
Another wrote: “He's happy because he is gonna be in the first team while Morata continues being a benchmark.”
But another pointed out: “This was in the presentation ceremony – could have been laughing at anything!”
It wasn’t the only memorable moment from the match, with Chelsea defender David Luiz hitting headlines for his outrageous header back to keeper Thibaut Courtois.
Following the defeat to their London rivals yesterday, boss Antonio Conte said: “We are working, we are trying to do our best.
“We had a tough pre-season, between the six days until we start the league it is important to be focused on the next game.”
