Dack's manager at Gillingham between 2015 and 2017, Justin Edinburgh, described him as "the catalyst of [our] team...full of energy, he is tenacious, he has quality and he is a top player – definitely Championship quality", adding that he "probably covers more ground than any other player".[48][49]
