Merrett, who has been chosen to lead the side out on the weekend in the absence of the injured Brendon Goddard, says Heppell is the obvious choice to be the next captain.
“It was probably a bit of an underwhelming reaction to him (Worsfold) because I was such in shock,’’ Merrett said of being told of the news.
“It’s fantastic, it was obviously a bit of a surprise and something I definitely wasn’t aiming at to achieve this year.
“It’s a very good opportunity and I’m looking forward to it.
“But I think Dyson is probably the man for next year, he has been fantastic for this footy club so far so I think he is the man for next year.
“Dyson has done his apprenticeship last year and I think he is ready to go for next year.”
Merrett has enjoyed a standout season, averaging 29 disposals, 10.3 contested possessions and 6.4 tackles in just his third season in the AFL system.
