"Tonight's #UCL match between #mcfc and @borussia_en has been postponed due to adverse weather conditions," City said in a statement on their Twitter feed.

It had rained heavily in Manchester for several hours prior to the game's scheduled 1845GMT kick-off and there was thunder and lightning overhead as fans made their way to the stadium.

UEFA's rules state that if a match in the competition is postponed, a decision on when it will take place must be taken within two hours of the postponement.

The match must either be played the following day or on a reserve date.

UEFA's Champions League Twitter account wrote: "Further information on the rearranged fixture will be provided in due course."

A group of UEFA officials carrying blue umbrellas performed a pitch inspection around 45 minutes prior to the scheduled kick-off time.

Manchester City's goalkeepers Claudio Bravo and Willy Caballero had come out to warm up, but were ushered inside.

The rain eased off as kick-off time approached, but with the pitch sodden and conditions outside treacherous, the decision to call the game off was made shortly before 18:30 GMT.

Manchester's Metrolink tram system had to be temporarily suspended and photographs circulating on social media showed huge puddles in city centre streets.

The match is due to be City manager Pep Guardiola's first group-stage game with the club.

City and Gladbach met in last season's group phase, with the English club winning both games en route to the semi-finals.
