Peeved Ally McCoist admits Rangers' below-par display against Aberdeen had him feeling blue on Tuesday night.
The 59-year-old was keen to quickly move on from his former team after they came up short during the 1-1 draw at Pittodrie.
And McCoist admits Gio van Bronckhorst's side were just part of a night to forget as his second team Chelsea also came up short away to Brighton.
It's not all doom and gloom for Rangers, however, who remain four points clear at the Scottish Premiership summit, but there is plenty to work on after Ianis Hagi's opener was cancelled out by Lewis Ferguson's second half penalty.
And McCoist admits he can't see the positives right now.
Speaking on talkSPORT, he said: "I was so disappointed in both my teams last night, they were rotten, they were rotten man, Chelsea, and Rangers were worse.
"I don't want to talk about either of them, move on, I've annoyed myself."
Rangers get the chance to spark an instant response when they host Stirling Albion in the fourth round of the Scottish Cup on Friday night.
