Roberts has gone back to his parent club Manchester City following an 18-month loan spell at Scottish Premiership giants Celtic.
The 20-year-old winger was one of the best players for the Glasgow giants last season, helping Brendan Rodgers’s side win the Scottish Premiership, the Scottish League Cup and the Scottish Cup.
If Celtic secure the services of Roberts for the 2017-18 campaign, then it will mean more competition for Forrest, who has been at the Bhoys his entire professional club football career so far.
The 26-year-old Scotland international, though, has suggested that he is ready for the competition he could potentially face from Roberts.
“At a big club like Celtic they are always looking for players for every position and to better the squad,” Forrest told The Scottish Sun about Roberts.
“He’s been linked with a move back here ever since he went back over two months ago. All the boys have been aware of that but at the moment he’s still at City so we will just wait and see.”
