Chennaiyin FC suffered second successive defeat in the league on Tuesday night, courtesy of Sergio Lobera's Mumbai City FC. 

The Chennaiyin fans were left frustrated by what they perceived to be another shambolic officiating. 

Plenty took to Twitter to hit out at a number of key decisions that went the islanders way at GMC Stadium, Goa.

Well, we'll let Chennaiyin fans do the rest of the talking...

There were very, very, very, very, very, very bad decisions.

Another evening of horrific refereeing.

The saga of referees ruining football continues at the @IndSuperLeague #MCFCCFC

Another day, another poor refereeing performance. By far the most pressing problem that needs to be address#isl #MCFC #MCFCCFC #chennaiyin #IndianFootball

Wow! @ChennaiyinFC have been screwed big time. Mumbai take an undeserving lead. #MCFCCFC #ISL

Chennaiyin getting absolutely robbed here. Looks like Mumbai City have given the refs some of that sweet oil money #MCFCCFC #ISL

Clearly it is possible to be high on oil

Absymal refereeing, two penalties denied, zero red card. But it all feels numb. Too many times, I guess. Players gave absolutely everything. Chin up @ChennaiyinFC very good performance. #AllInForChennaiyin #MCFCCFC

Taking their chances is in a team's hands while taking correct decisions isn't in theirs. Refereeing is a topic fans love to discuss until the cows come home. I can perfectly understand their feelings but I would rather worry about something which is under my control. #MCFCCFC
