Giacomo Raspadori scored twice as Napoli came from behind to deliver a masterclass and score a runaway 6-1 win at 10-man Ajax in the Champions League on Tuesday. The captain, Giovanni Di Lorenzo, Piotr Zielinski, Khvicha Kvaratskhelia and the substitute Giovanni Simeone added the other goals for the Italian league leaders, after Mohammed Kudus had given the hosts the lead inside the opening 10 minutes. Napoli, who might have scored more such was their dominance, have a 100% record at the halfway point in Group A, leaving Ajax with three points from their opening three games and in danger of missing out on next year’s knockout stages after their biggest defeat in European football. Internazionale bounced back after two consecutive losses in Serie A with a crucial 1-0 win against Barcelona thanks to a Hakan Calhanoglu goal. The midfielder slotted home a clinical strike from just outside the area, with the ball going into the corner to the goalkeeper Marc-André ter Stegen’s right in added time before the break. The home win lifted Inter to second place in Group C on six points, three behind leaders Bayern Munich and three in front of Barcelona. Bayern struck three times in the opening 21 minutes en route to a 5-0 demolition of Viktoria Plzen to set a record for the longest unbeaten run in group matches. The German champions have now gone 31 group games in the competition without defeat. Elsewhere, goals from Club Brugge forwards Kamal Sowah and Ferran Jutglà saw the Belgian champions beat Atlético Madrid 2-0 at home to extend their perfect run in Group B this season. The hosts took the lead in the 36th minute when Jutglà’s low pass across the goal found Sowah, who tapped the ball into an empty net for his second European goal in three games. Jutglà doubled the lead in the 62nd minute after winger Tajon Buchanan calmly waited for the right moment to set up the Spanish forward inside the box. Atlético had a chance to get back into the match with a penalty 15 minutes later but Antoine Griezmann lashed the ball against the bar and moments later the forward thought he had scored but his effort was ruled out for offside. Porto substitutes Zaidu and Galeno were both on target as they beat Bayer Leverkusen 2-0 to seal the Portuguese side’s first victory in the group stage. They are level on points with Leverkusen after three matches. Marseille secured their first Champions League win of the season when they recovered from a shaky start to outclass 10-man Sporting 4-1 in an incident-packed Group D encounter at an empty Stade Vélodrome. The game, played behind closed doors after crowd trouble marred Marseille’s home match against Eintracht Frankfurt, was delayed by more than 20 minutes following Sporting’s late arrival at the stadium due to a traffic jam.
