Tony Mowbray insists he has no concerns with his side's home form despite Celtic's Co-operative Insurance Cup quarter-final defeat by Hearts leaving him with only two wins in nine attempts at Parkhead since taking over from Gordon Strachan in the summer.

Jambos midfielder Michael Stewart, booed by his own fans during Saturday's goalless draw against Falkirk in the Clydesdale Bank Premier League, put the visitors ahead from the spot in the 58th minute after Hoops left-back Danny Fox had tripped Christian Nade inside the Celtic box.

However, once again in front of their own support, albeit a vastly reduced crowd of around 20,000, Celtic missed numerous chances before the final whistle brought a crescendo of boos down on the home players.

"The performances will suggest if it (home form) becomes a problem and I didn't see a lack of belief in the team," Mowbray said. "I think we would be concerned if we weren't making chances but we are making chances every game we play and it will click.

"I've seen a very positive team playing against a team who deserve credit for defending as well as they did. We played very positive football and deserved better than we got to be fair.

"But when the chances come we have to be more clinical. Sometimes you have to understand that when it's not rolling your way, it's not rolling your way and I believe that the players will do that."
