Celtic's Neil Lennon determined to find answer to poor SPL form They don't contribute anything to the game up here and just want to take the negatives out of it. I am prepared for it, I've seen it all before and I've been in a lot worse position than this. One point out of nine at home is not good enough, so I sympathise with them (the fans) - but they have to sympathise with us sometimes, too. It's not that the players are not trying to win the game or that they are lackadaisical, or lazy - it's just that it has not happened at times. I need to get my finger on the pulse and find out why. Georgios Samaras was also on hand - with the demeanour of a man having a tooth pulled without anaesthetic - to offer thoughts, if not clarity, on the dichotomy between Celtic's form at home and in Europe. Asked if it was easier to engage mentally with the task of facing Barcelona than Caley Thistle, he retorted with a reading from the Book of Cantona. It's nothing to do with mentality. To be honest I hate that word. I don't agree that the mentality isn't right or with that word," said the Greek striker. I know it's difficult to go from Champions League to SPL but that's football, that's the reason we're professionals. We need to switch on and be more focussed and try to play our game. Psychology is a totally different thing from mentality. People might use mentality as an excuse. I'm not a believer in that but psychology is something else. When you're psychologically high you're feeling good about yourself and feeling positive. That's a totally different thing than your mentality. You can't compare them or put them in the same cup. Of course we need to be in good psychological condition to do well and I think we are. But I don't believe we have a problem regarding mentality. Meanwhile, the Hearts manager, John McGlynn, does not believe Lennon is under additional strain at Parkhead and is ready for a similar reaction to when Celtic were narrowly beaten in Barcelona and lost to Kilmarnock the following weekend, before bouncing back with an emphatic 5-0 midweek win over St Johnstone. "I don't think he's under any pressure," McGlynn said. If they've maybe taken their eye off the ball a wee bit in defeats like Saturday, they end up coming out on the Wednesday night and in one of those situations taking five goals off St Johnstone. Sometimes it just takes a wee kick up the backside to bring you back down to earth. There's been a reaction to their defeat which will certainly have them fired up. When they come to Tynecastle they know they have to be at the top of their game. That's something we have to be very aware of and be prepared for. Should Hearts win - and the odds are against such an outcome, despite the vagaries of Celtic's form - McGlynn's men would move to within four points of the champions. "We'd have probably taken that at the start of the season, four points behind Celtic entering December," McGlynn added. It could go 10 points - I'm not daft - but we've got an opportunity to close that gap. Everyone would be delighted if we were to do that, because it may well be there's a new leader at the top of the table going into December. It's good for the SPL. It's good there's competition in the SPL. Hearts, will have to do without Danny Grainger for around three months after the left-back suffered a partial tear of his anterior crucial ligament in Saturday's 0-0 draw at Motherwell. "We're hoping he's not going to need surgery," McGlynn added. I'm gutted for Danny that he's going to miss a good part of the season. He's one of our top goalscorers this season with three goals from left-back, which is an excellent return.
