Celtic defender Alexandro Bernabei has endured a tough start to life in Glasgow, with off-field issues and a lack of game time having previously seen the Argentine struggle to make an impact in his new surroundings.

The former Lanus man - who arrived at Parkhead on a £3.75m deal in the recent window - had been brought in as cover and competition for first-choice left-back Greg Taylor, although has struggled to dislodge his colleague as a result of the Scotland international's "consistent" displays, as lauded by teammate Matt O'Riley.

Amid the need for rotation ahead of a hectic run of fixtures, manager Ange Postecoglou handed the youngster a rare chance to impress in Saturday's Scottish Premiership clash away at St Johnstone, with the 22-year-old's only other league outing having come as a late substitute in the 9-0 thrashing of Dundee United back in August.

On what was just his second start for the club - having previously featured in the League Cup win over Ross County - the attacking full-back no doubt took his chance, playing a crucial role in helping to steer the Bhoys to victory.

The £2.97m-rated ace had looked lively from the off as the visitors took control of proceedings, notably producing a brilliant cutback across the box early in the first half that his teammates somehow failed to get on the end of.

Such quality from down the left flank did prove fruitful late on, however - after Alex Mitchell had cancelled out Andy Considine's early own goal - with Bernabei producing a delightful whipped cross for Giorgos Giakoumakis to turn home right at the death.

That stunning assist - which was the defender's first goal contribution for the club - came at the end of what was an "impressive" all-round performance against Callum Davidson's side, in the words of journalist Josh Bunting.

The 5 foot 7 menace notably won 100% of his aerial duels despite his diminutive frame, while also recording two interceptions and one tackle to showcase his willingness to put in the hard yards defensively.

As Glasgow Live journalist Ben Banks noted in his post-match player ratings, the 124-touch gem provided real 'attacking intent' from his left-sided berth, with Postecoglou also lauding him as "very aggressive on the ball" after the triumph.

The Hoops boss also stated that the summer signing had "showed the attributes we really find exciting", with the 57-year-old likely keen to see just what kind of impact Bernabei can make in the coming games.

On this recent evidence, there certainly is a lot to be getting excited about.
