Luciano Spalletti believes Juventus' Europa League matchup with Rennes will be a "maturity test" for his side.Juve are top of the league phase table after two matchdays following a 5-0 win over NEC and 2-1 victory over Celta Vigo, but their Serie A form has suffered.The Bianconeri are eighth in Serie A after seven games following a 3-0 home defeat to Lazio, who are eight points ahead of Juve in second – level on points with leaders Inter.Juve have lost two of their last five Serie A home games (W2 D1), as many defeats as they recorded in their previous 44 top-flight matches at the Allianz Stadium (W24 D18).Nevertheless, they have won their last four home major European matches, scoring 12 goals and conceding two, and Spalletti desires a professional performance against Rennes.When asked why Juve's results have differed in Serie A and the Europa League, Spalletti said: "There's no specific reason. Every match has its own history, and you have to react to what the opposition brings each time.Working towards #JuveSRFC #UEL https://t.co/g4EK1JcPlv— JuventusFC (@juventusfcen) October 21, 2026"You need to understand the consequences of their approach and know when to press and when to stick back. We have to be more decisive when we make a choice."Rennes is strong on the open field and physically."They have fast attackers and the [Ligue 1] top scorer, Lepaul. They are having a good season; they are sixth, but one point below the top spot, so they have enthusiasm, and for us it is a maturity test."We must be good at determining things with our attitude."Juve and Rennes met in the 1999 UEFA Intertoto Cup final, with the Italian side winning 4-2 on aggregate (2-0 home, 2-2 away).In all European competition, Rennes have lost all four of their away matches in Italy, losing to a different team each time (Juve, Udinese, Lazio, AC Milan).The post Spalletti sees Rennes matchup as ‘maturity test’ for Juventus appeared first on SoccerNews.
