Andreas Hinkel says he plans to appeal to his former Celtic teammates to play Rangers eliminated from the Europa League.
The former Parkhead full-back was Domenico Tedesco’s assistant at RB Leipzig, who stood between the Ibrox men and made a sensational final appearance in Seville.
Hinkel told the Scottish Sun: “I’ve always been following Celtic and Scottish football since leaving the club.
“I’ve been watching the Old Firm vs Rangers game for the past few years.
“I have connections in Scotland and I still keep in touch with people like John Kennedy in Celtic.
“I’ll probably call a few people before the Rangers first game to talk about the team.
“We’ll be analyzing all of Rangers’ recent games but it can also be helpful to talk to someone like Kendo.
“He’s been involved against Rangers many times over the past few years and will be an expert on them.”
Hinkel, who was signed by Gordon Strachan in 2008, added: “Unfortunately, due to our schedule, I won’t be able to watch Rangers live before we play.
“But we will analyze them and we will get our information about them.
“We have a good analytics department who will monitor them and we’ll see what happens.”
Rangers had scouts at Red Bull Arena last night as a sold-out crowd watched RB Leipzig struggle to get past Union Berlin in the German Cup semi-final.
They needed a VAR penalty and then a late winner from Emil Forsberg – but they are now the favorites as they face Freiburg in the final as they search for their first trophy.
Leipzig meet Union again at the tournament on Saturday as they aim to consolidate a third place and a Champions League spot next season.
Tedesco’s side, currently 15 games unbeaten, will host Rangers next Thursday with a return to Ibrox on May 5.
