Celtic manager Neil Lennon was absolutely fuming after his side lost 1-0 at home to St Jonhstone on Sunday. The Hoops were inefficient throughout the match with Kris Commons having an early penalty saved by Peter Enckelman before he, and substitute Paddy McCourt, hit the woodwork in the second half.
Dave Mackay's 60th minute deflected goal was the difference between the sides, as the Saints won for the first in 13 years at Parkhead.
"I am angry, really angry," he said. "We threw it away. We missed clear-cut chances, were complacent and wasteful in front of goal.
"The longer the games goes on and it's nil-nil, you give the opposition encouragement.
"I'm fed up with it and fed up with us missing penalties, that would have given us a real good start.
"In the final third again we were awful. It was immature. That is one way to describe it.
"Paddy gets in and he has the whole goal to aim at and he hits the post and it bounces out to James Forrest and he panics and hits the defender.
"So there is a bit of that in our play at the minute."
And Lennon said it was not his defenders who should be blamed for the loss as his attacking players showed profligacy in front of goal.
"My back four gets the blame when a team scores and they don't deserve that," he added.
"My front six were bang average and I am more angry with them than anyone else.
"We hit the post a couple of times but we missed simple chances.
"We might not have deserved the result but we got it and if you don't take your chance that's what happens in football."
