Justin Longmuir believes young midfielders Andrew Brayshaw and Adam Cerra still have a lot of development to come to reach their best football. 

It’s an exciting prediction from the Fremantle senior coach, with the pair combining for 59 disposals in Freo’s 16-point win against Hawthorn on Monday night. 

Brayshaw’s 33 disposals was five more than his career best, Cerra was just as impressive with 26 disposals and a game-leading eight marks. 

Longmuir praised the pair, saying they're starting to see results from their work off the field. 

“It’s reward for effort for those two…they’ve worked their backsides off to improve their game and they’re bearing the fruit of that,” Longmuir said.

“Their attitudes to put in all they’ve got to every session they do to get better and improve their game, tonight is a by-product of that.

“I think you’re starting to see Cerra’s composure and his ability to hit targets that others probably can’t hit and Andy’s just playing to his strengths with his in and under, inside outs. 

“They’re both going really well so it’s just a product of the hard work they’re putting in.”

Brayshaw will play his 50th career game next Saturday night against Carlton at Optus Staidum while Cerra reached the milestone in round nine against Collingwood.

Longmuir believes that the 20-year-olds' best will come well after they’re well pass the 100-game milestone.

“It could even be a little bit later (than 100 games) to be honest, we are starting to see some really good players in the comp starting to get up to 100 games before they take a hold of games,” Longmuir said.

“So they are still young in terms of age, but a lot of maturity in terms of the people they are, on the field but off the field as well. They both had good nights tonight.”
