Celtic boss Ange Postecoglou oversaw the 50th Scottish Premiership victory of his tenure as his side ran out comfortable 2-0 winners away to Dundee United on Sunday evening, with the Parkhead giants restoring their handsome, nine-point advantage at the summit.

Having enjoyed a rare week of rest following the 5-0 thrashing of Greenock Morton last Saturday, the Scottish champions were in rampant mood at Tannadice yet couldn't make an early breakthrough, with Kyogo Furuhashi notably firing high and wide inside 30 seconds.

A frantic climax to the first half then saw an Aaron Mooy effort cleared off the line by Craig Sibbald after Reo Hatate's initial chip had struck the woodwork, while the visitors were then awarded a penalty on the stroke of half-time, only for the decision to be swiftly reversed following a VAR check.

With Liam Fox's men somewhat hanging on heading in at the break, the Hoops then struck a deserved, albeit bizarre opener just minutes after the restart, with Jota nodding in at the back post following a looping cross from Aaron Mooy.

The latter man then all but sealed the win just minutes later after cooly converting from the penalty spot, with teammate Jota having seen his dinked pass strike the hand of Kieran Freeman inside the area.

That proved the end of the drama, in truth, as Postecoglou rang the changes ahead of Wednesday's meeting with Livingston, with that late shake-up notably seeing recent arrival Oh Hyeon-gyu make his first appearance for the club in the closing stages.

Following what was a third win of the season for the away side against the Tangerines, much of the talk will rightly be centred around the goalscoring duo of Mooy and Jota, although there was arguably another unsung performer on the day in the form of Alistair Johnston.

The Canada international - who only officially joined the club at the start of the month - has made a smooth transition to life in Scotland thus far, having swiftly and impressively filled the void of the departed Josip Juranovic at right-back.

Having been afforded a consistent run in the side in recent weeks as a result of the injury woes of Anthony Ralston, the 24-year-old has more than taken his chance of late, with his £3.5m capture already looking like an astute piece of business for the Celtic Park hierarchy.

The former CF Montreal man was particularly impressive in his full-back berth against Dundee, having notably enjoyed an impressive 90% pass accuracy rate from his 120 touches, while also laying on two key passes as a marker of his creative prowess.

Not just an asset offensively, however, the tough-tackling titan also proved his worth at the other end of the pitch as he won two of his four ground duels and three of his six aerial duels, while his overall match rating of 7.6, as per Sofascore, was bettered only by the two goalscorers on the day.

Glasgow Live's Alan Galindo was also full of praise for Johnston in his post-match player ratings, stating that the Vancouver-born ace has 'started [his] Celtic career really well. Early marker laid down to be the main man after Josip Juranovic departure.'

The versatile defender - who can also feature at centre-back - may not have been the standout name at Tannadice, yet he certainly proved his worth yet again to his new club.
