It was Lennon who gave the 23-year-old his debut at Parkhead five years ago, and a report in the Daily Mail claims he is planning to bring the winger to Bolton.
Forrest has struggled with injury since breaking into the Celtic team, and although his talent is undoubted, there are fears that his development has stalled. He played just 29 games in the 2014/15 season, once again due to injury, and the signings of Gary Mackay-Steven and Stuart Armstrong in January placed his position under threat. He started to break back into the team towards the end of the season, but there are no guarantees that Ronny Deila sees him as a long-term part of his plans for the club.
This potential availability has opened up the chances of a potential move away from Parkhead, and Lennon is willing to take him to Bolton to spearhead a promotion push next term.
The Trotters released 13 players at the end of last term, with Lennon utilising the squad he inherited through the campaign, and he is planning on overseeing a major rebuild this summer to get the club back into the Premier League.
He is known to favour pacy attackers, and Forrest’s ability to cause trouble in the wide positions suits Lennon’s system perfectly.
With just one year left on his contract, Celtic could be open to selling Forrest, although the report does state that he would still cost a seven-figure sum to bring him to the Macron Stadium.
