Roberts, who has been Coleman's assistant since he was appointed Wales manager in January 2012, added: "He couldn't have taken on the job at a more hard time and what we've collectively achieved since then has been fantastic".
Coleman, who led Wales to a stunning semi-final finish at Euro 2016, is out of contract at the end of the season and he was evasive when asked if he might stay on.
According to Sky, several Wales players are keen for Coleman to continue at the helm and guide them through the EURO 2020 qualifying rounds and through the tournament itself should they qualify.
Although it was some 35 yards out, the positioning of it from the goal looked like a good opportunity to at least get the shot on target. "When the dust settles we'll see where we go", he added.
But Roberts insists the future of Welsh football remains bright despite their World Cup exit.
With three Champions League triumphs in the past four seasons, Bale is already arguably Britain's most successful footballing export, and yet he is under greater pressure at the Bernabeu than ever before.
