Celtic host the Bundesliga side in the Champions League on Wednesday.
Borussia Monchengladbach's Oscar Wendt
Borussia Monchengladbach defender Oscar Wendt has admitted that he is looking forward to meeting up with Celtic star and international teammate Mikael Lustig, before disclosing what the right-back has told him about the Hoops, The Scottish Sun reports.
The two sides will meet in the Champions League on Wednesday night at Parkhead. And going into the game which both teams will know could be crucial to their hopes of securing a place in the Europa League, Wendt has explained the reason Lustig gave as to why there is a much more positive atmosphere amongst the Scottish Premiership side this season.
Celtic's Mikael Lustig
"I know Mikael well from being in the Sweden squad with him and he's a very good friend," he said, as reported by The Scottish Sun.
"He has been at Celtic for a long time now and is a very good player, so I am looking forward to seeing him.
Celtic manager Brendan Rodgers
"All Mikael has said to me about Celtic is that they're enjoying working under the new manager."
The Bhoys' results this season suggest that there has definitely been a lift since Brendan Rodgers arrived. Celtic remain unbeaten in the top flight and have dropped points on just one occasion.
Meanwhile, they bounced back from the emphatic defeat they suffered against Barcelona in their opening game of the Champions League group-stages by securing a very credible 3-3 draw with Manchester City in their most recent fixture in the competition.
And that result will surely be giving them plenty of confidence going into what could be a key game for their hopes of remaining in Europe beyond the next four fixtures.
