St Johnstone manager Steve Lomas knows his side will face a difficult opponent tonight at Easter Road with the potent goal threat of Leigh Griffiths to contend with. The Northern Irishman would love to have the kind of goal threat that his opposite number at Hibs, Pat Fenlon, has at his disposal. Lomas is aware that, despite his off-field distractions, Griffiths knows his way to goal with 15 scored so far so far this season and is likely to be the biggest threat to the Perth side. He said: "Hibs have shown a big improvement from last season, when defensively they were poor, especially from free-kicks and corners. Pat has brought in some good players like James McPake, Paul Hanlon and Ryan McGivern whom I know all about, They also have Scott Robertson and the guy from Barnsley (Matt Done) and David Wotherspoon has been there for a while so they have some decent players and they have Griffiths up front. He is a goal scorer, a dogged and determined attacker and when a player like him is playing for you you always have a chance." Lomas got his first chance to see his latest your loan signings Mehdi Abeid and Gwion Edwards, who will be with the Perth side until the end of the season from Newcastle and Swansea respectively, when they came on as second-half substitutes against the Buddies in the Scottish Cup. The former West Ham and Manchester City midfielder is looking for them to put pressure on the more established players in his side in the second-half of the season. He said: "We got them in to increase competition and to compete for places in the team and a move to the SPL is good for them as well. We have lost a few senior players and the boys were very hungry, very keen to play here. The senior players know that if they don't perform then the boys are capable of coming in."
