Defeat was harsh on Fulham. They were brave, organised and efficient in possession. Silva sensed blood, was bold with his substitutions at 2-2 and no one could have grumbled if the Cottagers went on to win three points.But the best teams win when they are not at their best, and that’s what Liverpool did. They should have wrapped up the three points long before, with Klopp’s men sloppy in both boxes, chucking away goals at one end and missing gilt-edged chances at the other.Twice Liverpool led in a topsy-turvy but dominant first half that lasted for more than 56 minutes, but twice they chucked away their advantage with lacklustre defending and shoddy goalkeeping from Caiomhin Kelleher, playing in lieu of Alisson, who is out with a hamstring injury.His opposite number Bernd Leno took a knock to the head but soldiered on, hence the lengthy stoppage-time period, but the German had barely warmed up again when he accidentally diverted the ball into his own goal after Trent Alexander-Arnold hit the bar from a free-kick.After one Liverpool academy graduate put the Reds ahead, another pegged them back. Harry Wilson, who played for Liverpool from the Under 9s to the first team, ghosted into the penalty area and equalised for Fulham with a first-time shot that went through Kelleher’s legs.A wave of anxiety seemed to spread around Anfield at 1-1, with Fulham growing into the game and targeting Liverpool’s right-hand side. But just as frustrations grew, the Reds were ahead again through an Alexis Mac Allister thunderbolt.If fellow Argentine Alejandro Garnacho’s overhead kick last week was dubbed a shoo-in for goal of the season, Mac Allister will certainly run him close, as this piledriver from distance swerved away from Leno and into the top corner for his first Reds goal. He will do well to better it.Marco Silva’s side refused to lie down, though, and equalised for a second time in first-half injury time. Liverpool’s defenders were static, allowing Raul Jimenez’s flicked header to be diverted in by Kenny Tete, via a fumbled attempt to stop it from Kelleher.It was at this juncture that the old adage, ‘you don’t know what you’ve got until it’s gone’ felt pertinent. Alisson is not gone, of course, and is just suffering from a hamstring injury, but both of Fulham’s goals would have been bread-and-butter saves for the Brazil No 1. Jurgen Klopp expressed his joy as full time as he punched the air in front of a delighted Kop Mac Allister hit a looping effort from distance to score arguably the goal of the weekendLiverpool came out with more energy and intent in the second half and Nunez - who had earlier had an earful from his manager for losing possession cheaply - shanked one good chance on to the crossbar and fluffed another shot, both after fine passes from Salah.A game of 3D chess followed with both managers making a flurry of changes. Silva threw on Willian after his brace last week and Klopp responded by sending on Joe Gomez, a more defensive-minded full-back. Joel Matip was also forced off with a muscle injury.Fulham continued to grow in confidence, with Tom Cairney’s introduction giving them more impetus. They had several half-chances but seemed to lack a focal point up top. But Silva clearly sensed blood, and gestured for his players to go for a winner.The Cottagers thought they had managed to do just that on 80 minutes, after a fantastic counter-attack led by two substitutes, Willian and Cairney, and finished off by another, Bobby Decordova-Reid with a back-post header. Suddenly, Anfield was silenced.Liverpool had contrived to seemingly chuck away points. But Klopp was soon left in awe, glancing over towards the Kop, which was sent into bedlam after two goals in as many minutes turned the game on its head once more. Wataru Endo came off the bench to net the goal that looked to have saved a point for the hosts Alexander-Arnold secured his second goal in as many games after firing against City last weekFirst, with almost his first kick off the football, Japan captain Wataru Endo pulled Liverpool level with a deft, side-footed finish from the edge of the box. Less than two minutes later, Alexander-Arnold drove home Kostas Tsimikas’ header to win the match.Liverpool will not sustain a title challenge if they defend like this, but results mean more than performances sometimes. Today was one of those days. This is the ‘toughest period in football’ according to Klopp but this was a fine start to a run of eight games in 23 days.Wins like this won’t define whether Liverpool win the league but the next month certainly will dictate whether they can mount a challenge at least. They have 11 wins from 11 at home, with Manchester United, Arsenal and Newcastle to come at Anfield in the next month.So we will have a better idea of whether or not Liverpool are contenders or pretenders by the end of New Year’s Day, when Newcastle are in town. But one thing they certainly have is belief, with Klopp’s men already winning 15 points from losing positions. IT'S ALL KICKING OFF!
