Sadio Mane is available for Liverpool’s Champions League clash with Spartak Moscow tonight.
The attacker has been serving a domestic ban after he was sent off at Manchester City for a high boot on goalkeeper Ederson.
But he can play in Europe, prompting a debate as to whether boss Jurgen Klopp will unleash his ‘Fab Four’.
That would be Mane in attack alongside Philippe Coutinho , Mohamed Salah and Roberto Firmino .
Here, Andy Kelly from the Liverpool Echo has his say on how Klopp can spread fear into his rivals by starting the quartet together in Russia.
It's a starting line-up which will have been on many Liverpool supporters' minds since Mohamed Salah put pen to paper on June 22.
But circumstances have frustrated Jurgen Klopp in his attempts to try to get it on the pitch - until now.
The arrival of Salah for a club record £36.9m appeared to represent the final piece of an attacking jigsaw which simply whetted the appetite.
Salah on the right, Mane on the left, Firmino in the middle, Coutinho dropping a little deeper to feed them from midfield.
Mouth-watering.
The Egyptian has certainly upheld his end of the bargain, with six goals already under his belt, including Saturday's opener at the King Power.
That came from a wonderful assist from Philippe Coutinho, whose early season back problem (or strained neck as he peered towards the Nou Camp perhaps?) has been the principal reason why Klopp's number one line-has has only been on the pitch for seven minutes so far this season.
Once Coutinho returned to the fold, Klopp didn't deem him fit enough to be part of the squad for that damaging Premier League trip to Manchester City.
And even though the three game ban Mane collected at the Etihad didn't include the Champions League opener at Anfield against Sevilla, Coutinho was again only deemed fit enough for the bench, arriving after 76 minutes with Mane departing just seven minutes later.
Against Spartak Moscow on Tuesday night, Mane returns after completing his three game ban while it's difficult to imagine an in-form Coutinho not being given the opportunity to continue his reintegration into the Reds squad.
Moscow then represents Jurgen Klopp's first opportunity to see what sort of damage his preferred starting line-up can do.
Last minute niggles aside, surely it's an opportunity he won't turn down?
The Fab Four. Back in the (old) USSR.
