Leigh Griffiths scored his 40th goal of the season but it was not enough to stop Celtic slipping to a 2-1 defeat at St Johnstone. Griffiths flicked home the opening goal on 53 minutes but Saints equalised three minutes later when a blunder by Hoops midfielder Stefan Johansen allowed Steven MacLean to nip in for the equaliser.Saints then grabbed what proved to be the winner through Graham Cummins, who stabbed home from close range after goalkeeper Logan Bailly and Efe Ambrose got in each others way as they attempted to deal with a cross. Leigh Griffiths celebrates scoring his 40th goal of the season with his son Griffiths became the first Celtic player to reach the 40-goal mark since Henrik Larsson in 2004 and only the eighth in the clubs history to achieve the feat, with the striker doing so in his final game of the campaign as he is suspended for the clubs season finale at home to Motherwell on Sunday.The home side - who will finish fourth at the end of the campaign - applauded the champions on to the pitch then set about frustrating them.Only a fine save from Saints goalkeeper Zander Clark prevented Griffiths heading in a Christie cross at the back post before Tommy Wrights men created a couple of half-chances at the other end.After Bailly was penalised for sliding out of the box with the ball in his hands, Liam Craigs free-kick ended up at the other side of the penalty area where Brian Eastons shot was blocked in a packed six-yard box. Moments later, as the hosts broke, Chris Kane drilled in a low shot that flew the wrong side of the far post.The breakthrough finally came eight minutes after the restart when Johansen played the ball through to Griffiths and, after making his way into the penalty area and ghosting past two saints defenders, the striker flicked the ball home from eight yards with the outside of his left foot.Celtics lead lasted just three minutes, though, as Johansen was caught in possession as he dallied in possession in the area. Ryan Christie cuts a frustrated figure for the Hoops MacLean dispossessed him as the ball hit a divot before lifting the ball neatly over Celtic goalkeeper Bailly.Another sloppy mistake led to the winner, with substitute Cummins gratefully knocking the ball into the empty net after Bailly and Ambrose collided with each other.Ronnie Deilas side tried to come back but in the two minutes added time, Saints Clark made a double save, first from Callum McGregor and then Christie, to secure all three points.Watch Celtic v Motherwell on Sunday.
