Former Tottenham Hotspur boss Harry Redknapp has admitted he was nudged towards signing a top Celtic prospect while at the club.
The current QPR manager was discussing the state of Scottish football ahead of England's clash with the Auld Enemy this week.
"My chief scout liked the lad Forrest when I was at Tottenham and he drove me mad to sign him. He's suffered from injuries."
In the 2011/12 season, Redknapp's last at Spurs, he was voted as the SPL Young Player of the Year, but has gone onto make 31 SPL appearances across two seasons since.
This campaign Forrest has been on the periphery, starting just two games for Celtic to date, again because of injuries.
Celtic boss Ronny Deila said just last month: "We want him playing at full potential, so we are taking it slow. I can understand why they said he is a £10m player. He has things that very few others have in a one-v-one, skill and speed.
“What he needs is consistency. That is everything we’re working on, to try to keep him as long as possible on the pitch."
Perhaps the silver lining for Celtic is if it had not been for his injury issues, he may already have been snapped up, and if he can stay fit, they may yet benefit from his much-touted talent.
