The hapless way Liverpool gave up each of Wolves’s goals might have been taken from a West End farce. Alisson was the culprit for the gift that was Gonçalo Guedes’s opener, Ibrahima Konaté the man in the frame for the Hwang Hee-chan strike that takes this tie into a replay. Towards the end there even was a third comedy of errors when a Liverpool goalmouth scramble after a corner led to Toti putting the ball in the net only for offside to be given, puzzlingly. It emerged subsequently that the decision was against the taker of the corner, Matheus Nunes, to whom the ball had returned, though no TV angle seemed to confirm the decision. So it was that Jürgen Klopp’s men escaped. Seeing as he should rate the FA Cup as Liverpool’s best chance of a trophy this season – they trail Arsenal by 16 points in the Premier League, are out of the Carabao Cup and meet Real Madrid in the Champions League – he can feel relieved. Wolves, though, ended understandably furious – Julen Lopetegui was booked for his complaints – about the chalked-off finish. But, on this showing, the Spaniard should fancy Wolves’s chances in the rematch as Liverpool’s shaky rearguard appears to need a close-season reboot rather than a mid-season patch-up job. Klopp’s four changes included handing a debut to Cody Gakpo, his new £35m forward, who had Liverpool’s opening chance – a pea-roller of a shot that Matija Sarkic clutched with ease. More penetrative was a Mohamed Salah burst that caused Jonny to upend him outside the area but the Egyptian’s subsequent free-kick sailed over. This was Lopetegui’s fifth game managing Wolves and he was encouraged by a Rayan Aït-Nouri corner and another attack in which the same player fed Raúl Jiménez who, stepping into Liverpool’s danger area, was thwarted by a craftily deployed Konaté foot. The counterattack had a mirror image when Jiménez found Aït-Nouri, only for him to also be stymied. But then Wolves did score via Alisson’s clanger, after the goalkeeper sloppily passed straight to the lurking Guedes to finish. Conceding in this clownish manner was emblematic of Liverpool’s uneven season in which solidity and reliability are elusive. On the touchline, Klopp fixed on a grin but he surely seethed. From there Wolves began cuffing Liverpool aside. When Jordan Henderson was passed to in came Adama Traoré like a train to take the ball and leave the captain on the turf. Moments later, Traoré hurtled down the right and fired in a low cross that Jiménez was agonisingly close to tapping in. Gakpo appeared most likely to conjure an opening, as illustrated by one balletic touch-and-spin that put Liverpool on the attack. But he was isolated: considering Lopetegui had made nine changes and Anfield can be a cauldron, it was impressive from the visitors and far too passive from the home side. But at last Liverpool came alive and equalised from one of those sublime long-range deliveries Trent Alexander-Arnold finds easy. Nathan Collins bounced a clearance crossfield and the right-back took over, nodding the ball into his path before dropping a 30-yard diagonal towards Darwin Núñez. The striker’s awry finishing has been a recent satirical favourite but the way he volleyed past Sarkic belied this. The goal was as out of the blue as Wolves’s first had been and proved the last act of an entertaining first half. The first of the second period gave Liverpool the lead though they could thank a quirk of the offside law. Gakpo crossed and if it had gone straight to Salah the latter would have been in an illegal position. But because Toti intervened with a header that went to the No 11, who duly finished, his strike stood. Put another way: if the assistant referee had flagged instantly when the ball left Gakpo’s foot the game would have stopped then, and the scores would have stayed level. Liverpool were gleeful but again shot themselves in the proverbial. A dismal Konaté clearance allowed Wolves to attack. Hwang swapped passes with Matheus Cunha, Alisson was hesitant and Konaté pinballed the ball off the South Korean forward. Suddenly, this third round encounter was heading for a replay. It was a riveting spectacle but Klopp should be the far less content manager than Lopetegui at what he witnessed. Comments on this report will open shortly
