With Ange Postecoglou's Celtic side heading into Thursday night's Europa League clash in rather poor form, with the Bhoys having lost four of their last seven fixtures in all competitions, the 56-year-old Hoops manager would have undoubtedly been hoping for a positive performance and result against Bayer Leverkusen in order to kickstart the club's European campaign.

However, first half strikes from Piero Hincapie and Florian Wirtz gave the Bundesliga side a 2-0 lead at half-time in the fixture, before a 58th-minute Lucas Alario penalty and a stoppage time Amine Adli saw the visitors run out comfortable 4-0 winners, a result which leaves Celtic rooted to the bottom of the Group G table.

As evident from such a result, a number of Hoops players failed to impress over the course of the 90 minutes, with Kyogo Furuhashi, Tom Rogic and David Turnbull all receiving SofaScore match ratings of 6.4 or lower. However, it may be Cameron Carter-Vickers who is left most disappointed with his performance on Thursday night.

No tackles made

Despite having been in impressive form in the league for Celtic - with the centre-back averaging a SofaScore match rating of 7.60 over his three Premiership appearances, ranking him as the Bhoys' fourth-best performer in the top flight - the 23-year-old very much had a game to forget against Leverkusen.

Indeed, over the course of his 90 minutes on the pitch, the £1.8m-rated defender failed to make a single tackle, blocked no shots and made just one clearance, in addition to - perhaps unfortunately - giving away the penalty for Leverkusen's third goal of the match after being judged to have handled the ball in the box.

The £20k-per-week man also committed one foul, picked up a yellow card, ceded possession of the ball on 12 separate occasions and completed just two of his eight attempted long balls. These returns saw the Tottenham Hotspur loanee receive a hugely disappointing SofaScore match rating of 5.7, with no player from either team earning a lower score than the centre-back on the night.

As such, should Celtic wish to have any chance of qualifying from their Europa League group this season, Carter-Vickers will undoubtedly need to up his game over the club's remaining fixtures in the competition as, even more so than his centre-back partner Carl Starfelt - who also struggled on the night - the American badly failed his manager on Thursday.
