Celtic made it five Scottish Premiership wins in-a-row courtesy of a 2-0 win over Hearts.

It was the new boys who proved their worth on the day aa goals from £11 million man Arne Engels and a counter from Luke McCowan finally saw off Hearts stubborn resistance.

In a game of two penalties - one given and another overturned by VAR - it was deadline day signing Engels who proved to be the difference between the two sides after he kept his cool to slot home from 12 yards on 51 minutes for what proved to be the winner.

The Belgian internationalist opened his account for his new club by sending Hearts goalkeeper Craig Gordon the wrong way and slammed another effort against the post as he enjoyed a superb second appearance for the men in green and white.

However, Hearts will feel aggrieved that James Penrice was penalised for handball after the interval and Celtic defender Liam Scales wasn't in the opening period when referee Colin Steven overruled his original decision after consulting VAR.

It was substitute McCowan who popped up to wrap the game up when he started the move and finished it in style as he curled an effort in off the post from the edge of the box on 88 minutes.

Republic of Ireland international Adam Idah was denied his first goal since he rejoined the club and Celtic's third in injury-time when he netted from close range but it was ruled out by VAR.

Brendan Rodgers's men remain top of the Scottish Premiership table on 15 points alongside Jimmy Thelin's Aberdeen who continued their wonderful start to the campaign with a 2-1 win over Motherwell at Pittodrie.

Celtic will now switch their focus of attention to the Champions League league phase when Slovan Bratislava come calling to Parkhead on Wednesday night.

Kasper Schmeichel equals a slice of Celtic history

The Great Dane kept a clean sheet for the fifth league game in succession for the first time since Willie Maley was the Celtic manager in 1906. Kasper Schmeichel would also have breathed a huge sigh of relief when referee Colin Steven overturned his original ridiculous handball decision against Liam Scales which would have seen the shot-stopper facing a Lawrence Shankland penalty. He easily saved a swerving shot from Shankland when he dived full length to clutch. The 37-year-old equalled a slice of the club's illustrious history as he made it five clean sheets on the bounce. The No.1 has played seven games for club and country thus far this season and has kept a remarkable six clean sheets. That is outstanding form. The Celtic supporters loved Joe Hart. It hasn't taken them long to discover a new glove affair with Schmeichel. He got down low to save on the goalline in the closing stages as Hearts pressed for an equaliser. Schmeichel will be definitely feeling the love from the green and white hordes. He has enjoyed a fantastic start to his Celtic career and he will be looking to keep a clean sheet when he returns to the elite club level of the Champions League league phase on Wednesday night.

Arne Engels was cool as a cucumber when put on the spot

The Belgian international midfielder was making his first start and his second appearance for Celtic as he slammed an early effort wide of the target after great initial set-up work by Nicolas Kuhn and probably felt that he could have done better with the chance. He was further unlucky to also see a snapshot smash back off the post with Hearts goalkeeper Craig Gordon well beaten. The 20-year-old was caught in possession once in the opening 45 but had an uncanny knack for ghosting into the box and finding space. His timing, movement and spatial awareness were excellent as was his link-up play. He looks like a cool and calm customer and is very silky and elegant on the pitch. It was Engels who showed nerves of steel as he coolly slotted home the second-half spot-kick by sending Gordon the wrong way from 12 yards after the hosts were awarded a penalty for handball against James Penrice. What a way to open your account for your new club. He nearly scored with a cute backheel at one point. The £11 million deadline day signing from Augsburg possesses the talent and once he is up to speed he will prove to be a real asset to the Celtic midfield. He left the Celtic supporters wanting to see more.

Kuhn can be a killer by putting his shooting boots on 

German winger Nicolas Kuhn was a buzz bomb all afternoon. He attacked at will and he gave the Hearts defence a torrid time as he dragged players all over the place. He was positive and he was full of tricks and flicks and was always on the front foot. His movement stretched the Edinburgh men after the interval as he played on the shoulder as the game opened up. The biggest criticism of Kuhn was that he needed to be more direct in terms of his shooting. He can beat a player all ends up and manoeuvred himself into some great scoring positions, but he seemed reluctant to pull the trigger as he tried to play in his teammates. However, he chose the wrong option more often than not much to the frustration of the home support. If Kuhn can be more confident in himself and seize the opportunities when they present themselves then he will bag a barrowload. He has been a consistent performer with Celtic and Rodgers since pre-season and his levels are only going to go up and he will get better and better as the campaign progresses. If Kuhn can develop a more ruthless streak in and around the box then Celtic will reap the rewards.

Luke McCowan is living the dream

Trust McCowan to come on and help settle the nerves. The boyhood Celtic fan strolled on to the pitch and endeared himself to the supporters by notching the clinching second goal. Celtic were never really in much danger in this one and they did work Gordon a few times and peppered the goal with some shots on target. It could have been a lot easier for the hosts if Kyogo Furuhashi hadn't slashed the ball wide of target when played through one-on-one with only the former Celtic goalkeeper to beat. It was a more nervy affair than it needed to be towards the end and a second goal was what was needed and McCowan duly obliged. It was a great moment in sport as the 26-year-old started and finished the move. It is a moment he would have dreamt about all of his life. McCowan's smile which was as wide as the River Clyde told it's own story. The Celtic supporters would forgive him if they spotted him in McDonald's ordering a Big Mac rather than a bag of fruit this weekend. McCowan has earned it.
