Celtic’s disappointing start to pre-season continued on Friday, as they suffered a 3-0 defeat to Union Berlin in Germany.
An 11th-minute goal from Simon Terodde ensured the hosts would go in at the break a goal up, with Soren Brandy extending that advantage soon after the restart.
And the scoring was completed with three minutes of normal time remaining, when Damir Kreilach nodded home to consign Celtic to their fourth-straight defeat in pre-season.
Having seen his side lose fixtures against FC Sevastopol, CFR Cluj and Greuther Furth over the last week, Neil Lennon named a strong team in preparation for the upcoming UEFA Champions League qualifying clash with Cliftonville.
But the visitors were given a scare just three minutes in, as Patrick Kohlmann brought a fine fingertip save from Fraser Forster.
The Parkhead outfit did not heed the warning, however, and Forster was soon picking the ball out his net after Terodde stole in to score.
Celtic held firm to see themselves in at half-time just one behind, but it would take just 10 minutes for Brandy to elude the Celtic defence to score his side’s second.
Union Berlin had the ball in the net again soon after, only to be denied by the linesman’s flag, but they would eventually get their rewards for a fine performance with time ticking away.
The 2. Bundesliga side hit the post at the first attempt, but Kreilach produced a fine header at the back post in the aftermath to grab his side’s third.
