Celtic crashed to the fourth defeat of their German tour with Union Berlin running out 3-0 victors in the capital tonight.
The result was never in any doubt with Celtic finishing the match with youngsters Mikey Miller and Jackson Irvine in defence.
Both players had flown out to Berlin on Thursday to link up with the first team squad having played for the Development Squad in the 2-1 win at Inverness Clach on Saturday.
Scott Brown made his first appearance of the tour and lasted an hour with Tom Rogic probably the most impressive Celtic player on the pitch.
Playing at their new look Stadion An der Alten Forstere Union took an early lead when Simon Terodde smashed a 20 yard drive beyond Fraser Forster.
With Virgil van Dijk, Adam Matthews, Joe Ledley, Gary Hooper and Charlie Mulgrew watching from the stand the young Celtic side struggled to impose themselves as the home side were roared on by the majority of the 20,000 fans in the stadium.
Celtic survived to the break without any further loss but ten minutes into the second half a corner from the home side wasn’t properly cleared allowing Soren Brandy to net from close range.
The visitors did put together a couple of chances with a header from Irvine in the 66th minute almost producing a goal with Bahrudin Atajic and Liam Henderson introduced in the final quarter.
There was to be no consolation however with Damir Kreilach heading in a third goal for the home side in the 87th minute.
