Neil Lennon was delighted with his side's performance following their 2-2 draw with Livingston.
Celtic looked set to leave the Tony Macaroni Arena empty handed for the second time this season, but Tom Rogic secured a vital point inside injury time.
That goal means Lennon's men have increased their lead at the top of the Premiership table to 13 points, after Rangers suffered a shock 1-0 defeat against Hamilton Accies at Ibrox.
Speaking to BT Sport, Lennon said: "I'm absolutely delighted with the performance, and really annoyed with the two goals we gave away.
"Apart from that we were brilliant at a really difficult place to come, difficult pitch, but we were outstanding.
"You can see why Livingston get results here. They defend for their lives.
"I'm delighted with the relentlessness of the team. They just don't want to give up."
"But we were brilliant. Just the individual mistakes for the goals from players who've been absolutely brilliant for me this season, so that's the only bone of contention I've got.
"We always believed we'd score, and we did score and we deserved to score."
