Liverpool’s £64 million signing, Darwin Nunez, scored four goals in 45 minutes coming on as a second half substitute against RB Leipzig.

Three games into his Liverpool career, Darwin Nunez is officially up and running.

Bad news for the trolls and the social media ‘football banter’ accounts, for sure. They can park their memes and their GIFs and their Andy Carroll comparisons, at least for a few days.

Great news, though, for Jurgen Klopp. It may only be pre-season, but that familiar smile is back on the Reds boss’ face – and that can only be bad news for his opponents.

“He opened the box of Pandora!” beamed Klopp after Nunez opened his Liverpool goalscoring account in style on Thursday night, netting four times as the Reds thrashed RB Leipzig 5-0 in Germany.

How stupid the Uruguayan’s critics must feel this morning. It used to be said that new signings should be given six or nine months to settle in at a club, but that will never be the case in the Twitter age, where judgements are instant, definitive and so often downright ridiculous.

An hour’s worth of football was all it took for the keyboard warriors to emerge, labelling the £64 million ($75.5m) a flop for failing to find the net in 30-minute run-outs against Manchester United and Crystal Palace.

The usual accounts were full of it, posting ‘compilations’ of Nunez’s mistakes, while the word ‘Carroll’ trended, as rival fans compared the new-boy to another big-money Reds signing, one who managed only 11 goals for the club before being sold at a hefty loss.
