OWEN Hargreaves feels that Manuel Neuer's replacement Svein Ulreich could prove Bayern Munich's weak link tonight - assuming, that is, Celtic can get near enough to the Bavarian giants' goal to test him.

The Canadian-born former England midfielder, now a pundit for BT Sport, feels it would represent a "remarkable achievement" for Celtic to get a result in Munich but reckons one crumb of comfort is the absence of the world class Neuer with a long term injury.

Ulreich, he feels, could be vulnerable if Celtic can keep enough possession and get enough territory to test him.

“It would be a remarkable achievement if Celtic got a result in Munich," said Hargreaves. "It’s a big ask, especially with all the emotion of Jupp Heynckes coming back. They won 5-0 in his first game back and everyone is smiling again.

"But for whatever reason Bayern haven’t been at it this season and Manuel Neuer is missing which is a big thing. He isn’t incredibly busy but he makes important saves and the biggest weakness for Bayern is probably the fact he’s missing.

"But Celtic have to get up the pitch to test Sven Ulreich. Celtic blow teams out the water domestically but how much possession will they have against Bayern, 35 per cent?”

Hargreaves feels the financial and footballing gulf between Bayern Munich and Celtic has grown exponentially since he helped the German giants pip Martin O’Neill’s side to a last 16 place during the 2003-04 Champions League, first helping them fight back from the concession of an early Alan Thompson goal to break Celtic hearts with two Roy Makaay strikes in Munich that September, then carving out a grim goalless draw in the return match at Celtic Park.

But he also reckons that tonight in the Allianz Arena could prove the perfect setting for young men like Kieran Tierney and Patrick Roberts to take a giant stride forwards on the world stage, by proving they can cope with whatever the likes of Arjen Robben and David Alaba have to throw at them.

The Parkhead side again travel to Bavaria in hope, if not expectation, of the shock result which would open up this section, but even despite the early season turmoil which saw Carlo Ancelotti surprisingly replaced by Jupp Heynckes, Hargreaves feels the Germans deserve to be heavy favourites.

"We didn’t play the kind of dominant attacking football back then that this Bayern team does," he said.

"They have learned to win and have success in the Champions League, but not just win, they want to have success aesthetically, a bit like Barcelona. But Celtic are great to watch under Brendan Rodgers. It’s hard when a team is so dominant in their league and then they have to completely change the way they play against bigger teams such as PSG.

"But they are great to watch and have players like Scott Sinclair who has been terrific and everyone raves about Kieran Tierney. He’s one of those players who could easily play in one of the bigger Premier League teams and Patrick Roberts looks like he has the X-Factor in decisive moments.

“For young players playing in a game of this magnitude is a great test," he added. "I remember playing against Luis Figo in one of my first Champions League games and thinking ‘I hope he doesn’t destroy me’. But we won in that semi-final and it gave me so much confidence. While Bayern are heavy favourites, if Roberts or Tierney can get a bit of joy and confidence those young players can grow incredibly in a game like this. Hopefully they can spring a surprise because a lot of their players won’t know about them.”
