Bunn was part of the Villa side that got hammered 6-0 by Liverpool at Villa Park in the Premier League on Sunday afternoon.
The 31-year-old has taken to Twitter to assure the Villa fans that he will do his best for the team.
The Englishman has also made it clear that he is not bothered by the abuse he has been getting from the Norwich City fans.
Bunn joined the Villans on a free transfer in the summer of 2015 after leaving Norwich at the end of last season.

Bunn has made six appearances for Villa so far this season, keeping three clean sheets in the process.
The former Blackburn Rovers goalkeeper has made 1.67 saves per game and 1.11 saves per goal on average.
Villa are at the foot of the Premier League table at the moment with 16 points from 26 matches, eight points behind 17th-placed Norwich.
