Neil Lennon expressed his pride with the defensive record of his Celtic team, after Fraser Forster set a record for clean sheet minutes in the Scottish league. Forster surpassed Bobby Clark's 43-year-old run of 1,155 consecutive minutes without conceding a league goal. Hearts' failure to score against Celtic here means Forster's unbeaten run now sits at 1,214.

"I'm delighted," said Lennon after Leigh Griffiths and Teemu Pukki sealed Celtic's 2-0 win. "I sit here a very proud manager. We have just broken a long-standing record and it's a long-standing record for a reason.

"It's a great feather in the cap for the players and the club and obviously we maintain our unbeaten record in the league. Towards the end, when Hearts put us under a little bit of pressure, the intensity of our defending was very good. That has been the case for a considerable period of time. I am very proud of the players. In a season that has not been as good as last year, we still have plenty to talk about."

When asked if Celtic could continue their unbeaten run until the end of the league season, Lennon said: "That maybe a step too far but it's something that's really motivating the players and ourselves to try and achieve."

Forster shrugged off the personal significance of Celtic's run. "We defend as a team and attack as a team," said the goalkeeper.

Gary Locke, the Hearts manager, cited what he believed were two clear fouls in the build-up to Celtic's second goal. "How the referee didn't see that, I don't know," he said.

"There were a lot of positives for us today. You can see that the players are improving."
