Former North Melbourne midfielder Nick Dal Santo believes new Collingwood recruit Daniel Wells could put more effort in at training.

The Pies signed Wells to a three-year deal worth close to $1.8 million during last season's free agency period, although the 32-year-old is unlikely to feature in round one following a knock to his calf during a VFL practice match in February.

Wells and Dal Santo played together at North Melbourne between 2014-2016, and the pair spent time in the injury room together during the early part of the 2015 season.

Collingwood coach Nathan Buckley said it would be a "massive success" if Wells played 15 matches for the Pies each season during his three-year deal, although they were comments that Dal Santo struggled to understand.

"There's no secret he (Wells) could train harder, and probably more consistently. That will give him a better opportunity to play a majority of the games throughout the year," Dal Santo told Fox Sports on Tuesday.

"I recently heard Nathan Buckley say he'd be happy with 15 games – that surprised me, to say that we're happy with our new recruit, one of the best players in the League when he's fit, to be happy with 15 games. That means he's sitting out for seven in the regular season. That shocked me.

"I'd like to see him play the majority and if he needs to have a rest, one or two games, I can understand that."

Wells had an up-and-down final three years at Arden St before making the move to Collingwood, as he played 19 games throughout 2016 and made a huge impact for the club, but only played just 12 in the two seasons prior.
