The Light Blues assistant manager worked at Motherwell until February this year, and he has told the official Rangers website how he will be using his ‘inside information’ to give Stuart McCall’s men a boost in the play-offs.
Black said: “We have a little inside information about them having worked with a number of these players for the past few years. We will try and give as much information as we can to the players because we have good experience.
“There will be no stone left unturned with regards to preparation for Thursday and even more vital is the second-leg on Sunday.”
Black and McCall worked together in a management team for four years at Motherwell, and although the set-up has changed since then, Black is well aware of the current playing squad.
Having been with the Premiership team until as recently as February, Black is well aware of how Motherwell’s season has progressed, as they endured a tough campaign that saw them finish second bottom in the league table - having finished as runners-up last term.
He spent a spell of time with them under current boss Ian Baraclough, before leaving to link up with McCall at Rangers, who are looking to get back to the top flight by defeating Motherwell.
The two-legged final starts on Thursday, before the second leg is played on Sunday, and Rangers are certainly on a strong run of form heading into the game.
They will be motivated to secure their place in the Premiership next season, whilst Motherwell will be fighting for their lives looking to retain their top flight status, and Black’s knowledge of the current set-up could prove vital in securing a victory over his former employers.
