A lot has changed at Anfield since August 2015.
But, as the wounded beasts from Bergamo took a measure of revenge for that 5-0 dismantling a few weeks ago, Liverpool are mourning their heaviest home defeat since West Ham United cruised to a famous win on the red half of Merseyside more than five years ago.
Jurgen Klopp’s defence has been ravaged by injury and the absences of Virgil van Dijk, Joe Gomez and Trent Alexander-Arnold were clear to see.
Atalanta captain Papu Gomez had an inexperienced back line dancing to his tune, setting up the opener for Josip Ilicic on the hour mark before helping to create the second moments later as Robin Gosens arrived unmarked to slam home from close range.
Left-back Kostas Tsimikas left Ilicic free to score Atalanta’s opener while Neco Williams understandably found life tough against Argentina international Gomez, one of the most influential playmakers on the continent.
And Costacurta, a five time European champion with AC Milan, believes Atalanta took full advantage of Liverpool’s “weak points”.
“Go hit the weak points. Tsimikas and Williams are two guys who don’t play often (and played) for the first time together. Consequently, you have the ability to create so much,” said a man with seven Serie A titles on his CV.
While Liverpool’s youngsters struggled to contain Atalanta at the back, the Reds also mustered little threat at the other end.
Despite the presence of Sadio Mane, Mo Salah and Champions League hero Divock Origi, the hosts failed to produce a single shot on target in 90 minutes.
“Liverpool didn’t have shot in the first half, in the second there was only one chance,” Costacurta adds.
Liverpool are now just two points ahead of Atalanta and Ajax with two games remaining in the group stage. They take on the Dutch giants next week.
