England's coach, Trevor Bayliss, has said that his players "will not back down" in the event of further confrontations, following Jos Buttler's heated argument with Bangladesh's fielders during the second ODI on Sunday.

Buttler was reprimanded by the ICC match referee, Javagal Srinath, while two Bangladeshis - the captain Mashrafe Mortaza and Sabbir Rahman - were fined 20 percent of their match fee for "using language, actions or gestures which … could provoke an aggressive reaction", following Buttler's dismissal in England's 34-run defeat at Dhaka.

Tempers remained frayed after the match, with Ben Stokes tweeting his displeasure that one of the Bangladeshi fielders - reportedly Tamim Iqbal - had bumped shoulders with Jonny Bairstow during the post-match handshakes.

While Bayliss said he did not encourage such behaviour from his players, he added that England would not be changing their ways ahead of the series decider in Chittagong on Wednesday - and added that the ICC sanctions were a good indication of where the blame lay for Sunday's scenes.

"Don't forget there are always two teams in this type of argument and some of the teams around the world are not quite as pristine as they might like to make out," he said. "We are not going to back down from anything and certainly we have some characters in the team who will not back down.

"I haven't read the match referee's report but they were fined and Jos was warned for retaliating and that in itself tells a bit of a story. I think Jos wearing the captain's hat was not going to take it lying down. He got a slap on the wrist and I am sure he will be doing his best to stay out of trouble in the future."

The sight of Buttler losing his cool was notable in itself. Despite his raw power as a cricketer, he is one of the more softly spoken members of the England team. However, Bayliss was not unhappy that a steelier side of his character had been revealed to his team-mates.

"Since I have been here it is the first time Jos has been warned and his role is a little different to what it has been in the past," Bayliss said. "I think he has every right as captain to back his players up.

"You only have to watch some of our pre-match football matches to see the passion he has got. I have no qualms about the passion he shows. He has to be a little more careful about how he reacts, [but] he gets respect for that as well from the rest of the guys. It is a case of just watching what he says and the way he reacts to that."

The teams arrived in Chittagong today having flown in the same plane - and sat across the aisle from one another - and with the series tied at 1-1 following England's dramatic fightback in the opening contest, there will be no shortage of incentive for either side to land the knockout blow. Bayliss, however, urged his players to focus their aggression, especially given the anticipated passion in the stands.

"I think when playing in the subcontinent, with the crowds and the heat and that type of thing, some of these things can get out of proportion a little bit," he said. "We have got to be on the look-out to make sure it does not distract us from the way we want to play the game, and concentrating on what we do. We have spoken about it before, when the Pakistan series started, and there will probably be a reminder from the coach leading into the third game."

Reflecting on Sunday's loss, Bayliss admitted that England had shown a little bit of inexperience, particularly with the bat, but added: "The lesson from both games is that Bangladesh are no pushover. They have a very good team, a very good bowling attack playing in home conditions. A number of the teams have found out over the last 12-18 months they are no push-over. A lot of teams will be reassessing how they approach matches against Bangladesh in the future."
