Celtic fans finished last night with an all-too-familiar feeling - two points dropped due to individual errors. And the focus of their ire is on one player: Efe Ambrose.
The Nigerian defender made two mistakes last night, which led to two goals against Celtic and a draw snatched from the jaws of victory.
It's not the first time that Ambrose has made mistakes to cost Celtic a goal, or even a win.

If you read any Celtic message boards today, or the Twitter accounts of any fans, it's clear that they have lost patience with the player signed from Israeli league side Ashdod in 2013.
Many argue that the sight of Ambrose in the Celtic line-up leads them to believe that a mistake is bound to happen at some point during the game - and the evidence is stacking up to prove them right.
Time up for Ambrose at Celtic?
Ambrose is not a bad footballer. To be a mainstay in a very good Nigerian national team, as well as turning up through the gates of the Scottish champions, shows this.
Indeed, he has produced some stellar performances. However, his concentration is suspect and this has led to a few serious mistakes.
Unfortunately for Ambrose, most of his mistakes have been severely punished.
With even the manager Ronny Deila slamming his defender in the wake of the game last night, it leads you to think that his days at Celtic are surely numbered.
It seems that Celtic will be shopping for a new defender in the January sales.
