It's not the Etihad Stadium or Nou Camp, but tonight Borussia Park will be every bit as demanding of and unforgiving for Celtic's Champions League hopes.

The losses of Kolo Toure and Jozo Simunovic will further stretch Brendan Rodgers' resources and the resolve of a new look back line.

Gladbach's 2-0 win in Glasgow a fortnight ago was much more emphatic than the scoreline suggests. Being written off going into tonight's match won't cause Rodgers too much concern, though - ensuring that his side do themselves justice is more his style.

As soon as the final whistle went the Celtic boss was analysing where the match had been lost. There was no ranting, raving or tantrums but in his own determined way, he made his points known with Chris Davies yesterday explaining why tonight's match isn't mission impossible...

AVOID UNFORCED ERRORS

There's no margin for error tonight. Much as Gladbach dominated the match at Celtic Park they were presented with two goals that were avoidable.

While Rodgers likes his side to play an expansive game that doesn't extend to taking undue risks in defence. Kolo Toure will have learnt his lessons, his team-mates will know better than to risk a repeat tonight.

Playing a percentage game away to fancied opponents can swing the match in Celtic's favour. Gladbach will pose enough questions of their own without self-inflicted problems.

BACK BROONY!

The Celtic skipper was quickly closed down in the first match between the teams with Andre Schubert doing his homework on the Bhoys' 3-3 draw with Manchester City.

Brown has found a new dimension to his game this season, a level that allows him to transfer his domineering style from the domestic game into the highest possible level.

If Stuart Armstrong and Nir Bitton can get on the ball then Brown is capable of getting forward to ask questions of the Gladbach defence.

TAKE ANY CHANCES

It would have been an act of daylight robbery, but Celtic really should have scored through Scott Sinclair shortly before half-time a fortnight ago.

Tom Rogic's pass cut the Germans' defence wide open and Sinclair's anticipation and run was perfect, yet unfortunately the finish was from the Filip Sebo manual.

Chances don't come along too often in the Champions League, so it's critical to take advantage of moments of magic like Rogic's pass.

FEED THE MOUSSA

After the reaction to his performance and goals against Manchester City, it seemed as if Moussa Dembele could sink Gladbach on his own. Unfortunately for the Scots, Schubert had done his homework, praised Dembele then isolated him by suffocating the supply chain.

Getting the attacking midfielders close to the sole striker is essential. Keeping the team fluid, the ball rolling forward will ask questions of the home defenders who were given an easy time a fortnight ago.

THRIVE OFF THE ATMOSPHERE

Over 6,000 Celtic fans are having a ball today in Monchengladbach, some of them even have tickets for the match!

There will be an incredible atmosphere in the ground with the travelling support making their own contribution.

These are the nights to savour, to embrace, to enjoy, to revel in. It's not Molde or even Ross County, after all. A great stadium, a country steeped in football tradition and  two passionate sets of supporters - it doesn't get much better.
