Moussa Dembele revealed his misery on Twitter after Celtic slipped to a home defeat in the Champions League.

The Scottish champions were beaten 2-0 by German side Borussia Monchengladbach and failed to replicate their performance against Manchester City.

Celtic earned a 3-3 draw with the English giants in their last home European game, but were humbled by a well organised side on Wednesday night.

Lars Stindl and Andre Hahn scored second-half goals for the visitors to earn three points, with defender Kolo Toure making errors in the build up for both crucial moments.

The result leaves Celtic bottom of their group stage, with Barcelona extending their position at the top with a comfortable 4-0 win against Man City.

Dembele, who scored twice against Man City, endured a difficult night in attack against Gladbach and expressed his disappointment after the game.

“Tonight wasn’t as great as last time for us. Sad with the final result… Big thanks to the fans for the support,” Dembele wrote on his personal Twitter account.

Dembele has made a great start to his Celtic career despite a setback in the Champions League.

The 20-year-old has netted an impressive 13 goals in just 19 appearances since his move from Fulham.

He is currently keeping striker Leigh Griffiths restricted to substitute appearances and will hope to lead the line in their next match in the Scottish League Cup semi-final, when they face Old Firm rivals Rangers.
