Juventus manager Luciano Spalletti has delivered a scathing assessment of his side’s performance following their 2-0 victory against Pafos in the Champions League, labelling parts of their first-half display as "embarrassing". The Italian tactician lamented that his players missed "easy balls" and struggled defensively, necessitating a tactical reshuffle involving Weston McKennie to shore up a fragile backline.While three points in the Champions League usually calls for celebration, the mood in the Juventus camp was decidedly sombre following their latest European outing against the Cypriot side. Despite securing a victory that keeps their slim hopes of a top-eight finish alive in the league phase, the Bianconeri were far from convincing, leaving their manager fuming at the technical poverty and defensive fragility on display. Spalletti refused to sugarcoat the evening's events during his post-match media duties, making it clear that while the result was necessary, the method of achieving it fell well below the standards required at the elite level of European football. The primary source of Spalletti’s ire was a disjointed first-half performance where Juventus seemed unable to string passes together or control the tempo of the game. For a coach who prides himself on fluid, possession-based football, seeing his side struggle with the basics was a bitter pill to swallow.Speaking to Sky Sport after the whistle, Spalletti offered a brutally honest verdict on the initial 45 minutes, saying: "It was fundamental to win and with victories, things are put right. I am not happy and neither are the lads, we could and should have done more. We did the bare minimum, in the first half there were also embarrassing situations. Then after the goal, we had more tranquillity."Looking for smarter football bets? Get expert previews, data-driven predictions & winning insights with GOAL Tips on Telegram.

The injury crisis in defence forced the manager into uncomfortable compromises, most notably the deployment of Weston McKennie in a defensive role and the shifting of Pierre Kalulu.The balance of the backline was a major concern, with Pafos finding it far too easy to create goalscoring opportunities on the counter-attack. Spalletti’s analysis of his full-backs was particularly telling, highlighting the trade-off between offensive output and defensive solidity."Difficulty defending? It is true, we must also recover a right centre-back to let Kalulu play full-back and not McKennie," Spalletti explained.He reserved specific criticism for the defensive vulnerabilities on the flanks, noting that while Andrea Cambiaso offers a threat going forward, he can become a liability when facing dynamic wingers."Also Cambiaso is very offensive and struggles against players who cut inside," the manager added. "We conceded too much and exploited our qualities little, missing easy balls. For the moment it is like this, we take the second half."Add GOAL.com as a preferred source on Google to see more of our reportingThe victory provides breathing space, but it has not solved the underlying problems.
