Brendan Rodgers claimed he had never been angrier as a manager after watching Celtic’s “soft” first-half performance in a 3-1 Premiership comeback win over St Johnstone. Celtic trailed at half-time after conceding from an inswinging corner for the second weekend running. Diallang Jaiyesimi got the final touch as the champions struggled to deal with Graham Carey’s delivery. David Turnbull had Celtic’s sole shot on target in the first half as Saints threatened to take more points off the league leaders following a goalless Parkhead draw in August. With Mikey Johnston off the bench for Yang Hyun-jun, the visitors were much improved after the break. Callum McGregor and Matt O’Riley netted with powerful strikes before substitute James Forrest scored on the counter-attack in stoppage-time after Jay Turner-Cooke had come close at the other end. But Rodgers said: “I’m still angry, if I’m honest. The first half was nowhere near what you expect from a Celtic player and team. Just the level of intensity and ambition in the game, the speed, we were absolutely nowhere near it. We got bullied for the goal and we were soft in everything, with and without the ball. Half-time was the angriest I’ve ever been as a manager. “People who have been around me will know I’m normally very calm. It was nothing tactical - this was about desire and what it takes to play for this club. Thankfully in the second half the players were brilliant. Callum McGregor was outstanding and I got more of the energy and ambition that I want. “It was what I expected in the first half. We’d gone a game-and-a-half and not scored, with the greatest of respect, against St Johnstone. Craig (Levein) had organised his team well and they got their goal from the set-piece that we were soft at. I expect much more from us. “Second half, it was a real testament to the players, because they could have folded and been nervy, but they got to the level I demand from them. They were fantastic goals and we could have had more. It’s a reminder that if you go soft, if you go timid against any team, they can hurt you.” An Abdallah Sima double got Rangers back to winning ways with a 2-0 victory over St Mirren at Ibrox. Philippe Clement’s side had drawn in their last two matches against Aris Limassol and Aberdeen and the on-loan striker from Brighton quelled growing frustration in the stands when he broke the deadlock for the unimpressive home side with a strike just before the break. The Light Blues grew stronger in the second half and Sima grabbed a second in the 70th minute with a fine finish to take his tally for the season to 11, with Rangers moving back to eight points behind leaders Celtic having played a game fewer. Clement extended his unbeaten run to 10 games since taking over as manager but will require much more from his side if they are to topple the champions. Goalkeeper David Marshall produced an inspired performance as Hibernian defeated Aberdeen 2-0 at Easter Road to make it three wins on the spin. Striker Dylan Vente set the hosts on their way with his first goal since September before Will Fish’s second-half header sealed the points and tightened the Edinburgh side’s grip on fifth spot. Hibs were indebted to former Scotland goalkeeper Marshall who pulled off a string of vital blocks, including a penalty save from Bojan Miovski as the frustrated Dons remained 10th in the table, just three points off the bottom.
