Rangers suffered their second Old Firm derby defeat in just two months on Sunday – and their supporters reacted with disappointment on Twitter.

Moussa Dembele scored a 87th-minute winner to break the deadlock to secure a 1-0 win in the Scottish League Cup semi-final and clinch a place in the final against Aberdeen.

Celtic started the brighter of the two teams, Erik Sviatchenko had a goal ruled out in the first half before Scott Sinclair’s free-kick drew a save from Matt Gilks.

Rangers struggled to get on the front foot against the league leaders and were limited to counter-attacks but were not able to take advantage.

All-in-all it was a relatively subdued Old Firm derby and was nothing like the last encounter which saw Celtic thrash Mark Warburton’s side 5-1.

It was Rangers’ third defeat in four games after losing out to Aberdeen and Inverness in the Scottish Premiership prior to their semi-final defeat.

Rangers are some way off their rivals in the league, trailing by seven points and fans weren’t pleased to see them suffer another defeat in the derby.

However, it was an improvement on the 5-1 humiliation earlier this season so there were positives for supporters to take from the game.

Here is a selection of the messages on Twitter:
