Rangers’ Philippe Clement, Celtic’s Arne Engels & Hearts-Aberdeen in spotlight

Celtic continue to ride the crest of the Brendan Rodgers wave both domestically and in Europe after Wednesday’s 1-1 draw at home to an impressive Club Brugge inched the Glasgow side closer to the Champions League knockout stage qualification.

They have now gone 11 games without defeat since their 7-1 thrashing by Borussia Dortmund – their only defeat in 20 games this season – and are now two points clear at the top of the domestic table.

However, while their progress seems relentless and should continue beyond Saturday considering they have beaten visitors Ross County in their latest 12 meetings, there remain question marks about several positions.

With Adam Idah waiting in the wings, Kyogo Furuhashi’s strike rate is being questioned considering his five goals this season only makes him joint top scorer in the Premiership along with nine others – including County’s Ronan Hale, who also happens to have more shots on goal than any other player.

There is also a battle at left-back between Scotland cap Greg Taylor and on-loan Barcelona 20-year-old Alex Valle.

However, the main spotlight after midweek is in central midfield, where there have been calls from some pundits and supporters for Arne Engels to make way for Paulo Bernardo.

Engels made an impressive start after his multi-million pound August move from Augsburg but for the second time in recent weeks, Rodgers had to defend the 21-year-old Belgium international after another subdued midweek performance.

Meanwhile, his Portuguese team-mate, who himself completed a permanent move from Benfica this summer, has been showing his qualities off the bench.

Considering County have only ever won once at Celtic Park in their history and are without an away win in seven outings – and in 23 league games overall – their visit may be an ideal opportunity for Engels to regain his confidence.

Indeed, considering County have lost their past 11 visits to Celtic Park by an aggregate of 34-3, while Celtic have scored at least two goals in each of their past 21 league games – the longest such run of scoring in their history – the signs are ominous for the visitors whoever plays.
