We expected some big European nights at Anfield this season, just not this soon. Just months after the thrill of victories over Manchester City and Roma in the Champions League, Liverpool need to do it again and it is only December. At their famous old stadium, the Christmas lights are up in the huge windows of the redeveloped Main Stand. In the Premier League, meanwhile, Liverpool are top of the tree. But Wednesday night's game against the Italian dare-devils of Napoli feels definitive and its implications feel as though they will stretch beyond the boundaries of European competition. Win by the correct score and Liverpool will head into Sunday's domestic game with Manchester United feeling like their season has exploded in to life. Fail and not only will Jurgen Klopp and his players face the embarrassment of an early exit from a competition that gave them so much last season, they will also be thrown into the mish-mash of irrelevance and inconvenience that is the Europa League. To put it bluntly, Thursday night football next spring could ruin Liverpool's tilt at the Premier League title. The Thursday- Sunday-Thursday game cycle helps nobody. So when Klopp tried to present European and domestic football as two separate concepts ahead of the game, it was hard to buy the logic. Liverpool must beat Napoli to have any chance of reaching the knockout stages. They will qualify if they win 1-0 or by two or more goals. A victory by any other scoreline would see Liverpool having to rely on Paris Saint-Germain failing to win at Red Star Belgrade. If Liverpool win by any scoreline and PSG draw, those teams and Napoli will all have nine points. In that scenario, Liverpool's superior head-to-head record against Napoli and PSG would see them finish top. 'This is a different competition,' said Klopp. 'If we are not a Champions League club in February it will not be for one second an excuse for anything else. 'If we play Europa League or not even that — which is possible —then that is all it means. We do not need to make this game any bigger than it is, but it is big. 'This is an opportunity for us. Stay in the competition. The boys are desperate to stay in the competition.' A group that looked to have a health warning written on it as soon as it was drawn has grown ever harder for Liverpool on the back of poor away form. Unbeaten in the league, Liverpool have nevertheless lost three times away in Europe to be thrown into tonight's winner-takes-all fixture. The good news is that — barring injury to defender Joe Gomez — everything has gone right for Liverpool since they lost at Paris Saint-Germain two weeks ago. A last-minute winner against Everton has been followed by away wins at Burnley and Bournemouth, the latter featuring passages of the majestic form of last season. The bad news is that Napoli are a good side and manager Carlo Ancelotti is never short of motivation against Liverpool. 8 - Goals Mohamed Salah has scored for Liverpool in his eight Champions League games at home. Only Steven Gerrard, with 14, has scored more at Anfield in the competition The great Italian coach was manager of Milan when Liverpool shocked them in Istanbul in 2005 and again when revenge was taken in the 2007 Athens final. He also won at Anfield as Chelsea all but wrapped up the Premier League title in May 2010 and again with Real Madrid four years later, this time by a 3-0 scoreline. So Ancelotti knows his way round this stadium and brings with him a team who know they have a great chance if they score. Napoli have failed to score in just three games this season, so Klopp will hope Dejan Lovren has recovered from concussion to partner Virgil van Dijk. If not, Joel Matip, the weakest of their four central defenders, will have to play. 'You don't have a situation like this often in your career,
