Buttler is yet to move away from the concussion substitute controversy.
Buttler took a brutal dig during the toss for the fifth T20I between the two teams at the Wankhede Stadium, Mumbai.
When asked about his playing XI for the series finale, Buttler said there are "four impact subs" for England.
For the unversed, India replaced Shivam Dube with Harshit Rana midway through the second innings after he was hit on his helmet in the last over of the Indian innings in the fourth T20I.
The replacement sparked widespread reactions from experts, who claimed that Rana was not a like-for-like replacement for Dube. The pacer went on to play a critical role in India’s 15-run victory, taking three wickets on his debut.
While speaking to Ravi Shastri during the toss, Buttler remarked, "We going to chase. We have one change. Mark Wood comes in. And our four impact subs today are Rehan Ahmed, Saqib Mahmood, Gus Atkinson and Jamie Smith."
Former England captain Kevin Pietersen could not control his laughter at what Buttler said during the toss.
"It was real good. I don't think Ravi Shastri picked it up because of the noise in the stadium. It was very funny. He said that he has got four impact subs. Smart, very smart from Buttler. But I actually think the England team has dealt with it really well. The England team haven't moaned, haven't gone to press conferences and said things which they shouldn't have," Pietersen said during the broadcast for Star Sports.
"They have taken it on the chin. I think there would be a lot of aggression in their bowling. They are not going to make it easy for the Indian batters," he added.
Talking about the fifth T20I, England captain Jos Buttler won the toss and elected to bowl first. England and India, both made one change to their lineup.
The Three Lions introduced Mark Wood in place of Saqib Mahmood, while India replaced Arshdeep Singh with Mohammad Shami.
