The opener claimed that Sarwan wanted to take control of the franchise and that is why he engineered Gayle's ouster from the team.
"Sarwan, you are worse than the coronavirus right now," Gayle said in the video uploaded on his YouTube channel.
"What transpired with the Tallawahs, you have a big part to play because you and the owner are like this (very close). You were the one at my last birthday party here in Jamaica, giving big speech about how far we have come.
"Sarwan, you are a snake. You are so vindictive. You are so immature. You still stabbing people in the back. When are you planning to change? Don't even consider seeing the 'Universe Boss' and saying 'Yo Chris' because I am telling you this straight up, that's it," he added.
Gayle played his first four CPL seasons with Tallawahs before turning out for St. Kitts and Nevis Patriots in the next two seasons respectively.
He returned to Tallawahs the previous season as a marquee player before his alleged fall-out with the franchise that saw him join St. Lucia Zouks for the next season.
