Petrov said: "Hearts have a few problems with their manager but that is not our concern. We just need to keep the pressure on them.

"I hope their situation is going to be to our advantage but the only way we are going to win the league is by playing well and scoring goals.

I think it is good of Stan to come out and make a comment like this, and not being afraid to voice his opinions. I feel that he is right and it has burst Hearts bubble, i just hope that Celtic can now capitalise.
