Former Geelong great Paul Chapman has slammed Hawks fans for their treatment of triple premiership player Isaac Smith during the side's Easter Monday loss against the Cats.

Smith, who joined Geelong last off-season as a free agent after 210 games at Hawthorn, was met with a chorus of boos throughout his 15 disposal game.

In a tweet on Monday night, Chapman called out the frosty reception from Hawks fans.

"Hawthorn supporters - shame on you," Chapman wrote.

"A 3-time premiership player goes to another club and you boo him. Thank you Geelong supporters for being more understanding. Love you guys - respect."

Chapman, who played 251 games for the Cats between 2000-2013, moved to Essendon for the final two seasons of his career.

In a post match interview, Smith seemed unfazed by the reception he received.

"I was just thinking, 'Christ, if I get the shot after the siren, what's going to happen here?'," Smith told Seven.

Geelong coach Chris Scott praised Smith's performance in his new colours, admitting that the 32-year-old almost didn't play.

“He’s a confident sort of guy, and I thought our players really supported him,” Scott said post game.

“I don’t think there’s a player out there who’s being honest that doesn’t feel like there’s an extra edge to these sort of games – it’s very, very rare for a Hawthorn player to come to Geelong or vice versa.

“It wasn’t another game for Isaac Smith … but he only just made it to line,

“He was ill in the last couple of days, and that kind of added to the pressure a little bit for him and we had a few other issues as well.

“He couldn’t come to training yesterday, he was still pretty crook yesterday … clearly he was affected but I thought he was good for us.”

Smith has not been the first player this year to be given a frosty reception by former fans. In Round 1 Adam Treloar was notably booed by sections of the Collingwood crowd after a messy departure from his former club.
