South Korea\'s Ki Sung-Yeung was among the goal-scorers as Celtic made a confident start to their Scottish title challenge with a 2-0 win against Hibernian on Sunday. Ki netted Celtic\'s decisive second goal midway through the second half at Easter Road after Anthony Stokes had given Neil Lennon\'s team an early lead following a mistake from Hibs goalkeeper Graham Stack. Celtic\'s margin of victory could have been even greater but Stack partially redeemed himself by saving Gary Hooper\'s second half penalty. After being pipped to the title by arch enemies Rangers on the final day of last season, this was the ideal way for Celtic to kick off their bid to take the crown away from Ibrox for the first time in four years. Rangers had been held to a lacklustre draw by Hearts on Saturday and Lennon\'s side took advantage to establish an early lead over their main rivals in the title race. Lennon handed a debut to defender Kelvin Wilson after his move from Nottingham Forest, while his other new signings Victor Wanyama and Adam Matthews were on the bench. Sean O\'Hanlon made his debut for Hibs and Garry O\'Connor and Ivan Sproule made their second debuts after returning to Easter Road. Initially it seemed the earlier than usual start to the Scottish Premier League season might trouble Celtic and Hibs midfielder David Wotherspoon caused problems with an in-swinging cross that nearly crept in at Lukasz Zaluska\'s near post. Wilson then had to be alert to clear from inside his six-yard box and thwart the lurking O\'Connor. But Celtic were gifted the lead in the 14th minute when former Arsenal trainee Stack made a hash of catching a Kris Commons\' free-kick which slipped through his grasp and reached Stokes at the far post. The former Hibs striker showed great composure to take the ball down with his first touch and curl a shot high over the heads of several Hibs defenders into the roof of the net. Hibs tried to mount an immediate response and Wotherspoon had the Hoops defence panicking again as another teasing cross skipped past the far post for a goal kick. Colin Calderwood\'s team had their best chance to equalise early in the second half when Sproule latched on to Callum Booth\'s defence-splitting pass. However, Sproule allowed Wilson to catch him and end the attack with a well-timed tackle that brought desperate penalty appeals from the home fans. Ki, 22, showed him how to do it in the 63rd minute when he took a pass from Stokes and drilled his low shot past Stack from 25 yards to increase Celtic\'s lead. O\'Connor should have converted Sproule\'s cross moments later and Hibs\' woes looked set to continue when Celtic won a penalty after Emilio Izaguirre\'s clever check-back forced Sproule into a foul right on the edge of the area. But Stack kept the score down as he dived to his right to push Hooper\'s spot-kick on to a post before helping clear the rebound.
