Rangers' Harry Forrester
The Daily Record recently reported that he has been banished from the training ground and told that he can find a new club after falling out with Gers boss Pedro Caixinha.
And Nicholl - who won two Scottish Premiership titles with the Gers during his two spells with the club - has hit out at Forrester and suggested that the reports should act as a warning to others.
“Harry has been in and out of the team and has had injuries, but if he hasn’t been playing games for Rangers because of his attitude and application, then that’s horrific," he told the Evening Times.
“It should be a lesson to any young lad. If you get an opportunity to go to a club like Rangers, be on decent money and play in front of 50,000 every other week, then take it.
“Take time out of your life and dedicate yourself to football, because you’re a long time not playing."
It must be mentioned that the midfielder took to Twitter after the reports emerged and insisted that the speculation was not true, so it remains to be seen whether the former Doncaster man still has a future with the Gers.
Rumours and reports that I have been suspended are totally false and inaccurate— Harry Forrester (@harry_forrester) June 14, 2017
The 26-year-old has occasionally threatened to be a valuable player for the Light Blues, but with Caixinha overseeing a major overhaul of his squad this summer, it is not clear whether Forrester will get the chance to prove his critics wrong.
It appears that if the Record's reports are accurate - and, of course, Forrester has denied that they are - Nicholl feels in no uncertain terms that his chance has passed him by.
