The winger has featured in each of the nine games his side have played so far in the league, scoring a lone goal and setting up one more for his team-mates.
Hackett-Fairchild’s first goal of the campaign in the 94th minute of the match against Plymouth Argyle helped Portsmouth earn a crucial point last Saturday.
Cowley now feels the need for the 24-year-old to make the performance a benchmark and then try to raise his game to that level on a consistent basis.
He further recognises his coaching staff’s role in helping Hackett-Fairchild with that process.
“Reeco’s super talented – he lights up training every day”, Cowley was quoted as saying by The News.
“Honestly, I would say there’s not a passing week where he’s not the best trainer, on any given day.
“He’s a really talented boy and tactically really bright.
“We’re all working really hard to make sure that transcends on to the pitch because we know when it does we have a top, top player on our hands.
“It’s a challenge for all of us for that to happen – it’s his challenge and our challenge.”
Since joining Portsmouth in January 2020, Hackett-Fairchild has been out on two separate loan spells, at Bromley and Southend United.
He has still managed to feature in 47 games for Portsmouth, making ten goal contributions.
