Martin has already shown his worth throughout the opening two rounds of the season, with a man-of-the-match performance against Carlton and a strong showing against the Pies on Thursday night.
Cotchin believes Martin’s form won’t be bothered by the media speculation at all this season, and thinks the star midfielder will stay at the club beyond 2017.
“I don’t think he’s the sort of personality it will affect the way he plays, and I would like to think we’re mentally resilient enough to deal with anything that’s going on,” Cotchin said on SEN.
“There was obviously Rancey’s (defender Alex Rance) situation a few years back and other teams have been through it and it hasn’t affected performance, so I don’t think it will affect ours.
“I think he loves the club, I think he’s done a lot for our football club and we’ve done a lot for him and we’re just looking forward to him playing amazing footy, as he has done the last two weeks.
“Hopefully at some stage during the year, whether that be sooner rather than later or if it does have to be at the end of the season, he signs on and hopefully it’s for a long period of time.”
