Thursday's 3-3 draw at Porto highlights Manchester United's defensive woes, with 12 goals conceded in the first nine games. Recurring issues include giving away too much space in the box, defenders lacking aggression, and struggles with crosses. Each goal is analyzed and rated out of five for its awfulness. The Community Shield is excluded as it was only partially competitive. Erik, you might want to look away...

João Pedro's deep cross from the right went unnoticed by Harry Maguire, allowing Kaoru Mitoma to set up Danny Welbeck for an easy goal. United's failure to clear an injury-time corner led to Brighton's second goal, with Simon Adingra chipping a cross to João Pedro, who headed home calmly.

Casemiro's misdirected pass to Ryan Gravenberch gifted Liverpool a 5-on-3 advantage, leading to a goal. Casemiro was again at fault for Liverpool's second goal, being dispossessed by Díaz. Kobbie Mainoo's easy brush-off by Alexis Mac Allister led to another Liverpool goal.

Christian Eriksen's turnover allowed Sam Lammers to score, and Micky van de Ven's unopposed run led to Brennan Johnson's goal. Lisandro Martínez's failure to intercept Dominic Solanke's header resulted in Dejan Kulusevski's goal. Lucas Bergvall's corner led to Dominic Solanke's goal, and João Mário's cross allowed Pepê to score.

United's struggles with crosses continued, with João Mário's delivery leading to Samu's goal. Pepê's pace allowed him to set up Samu for another goal. Only Maguire's late header prevented a further embarrassment, but with a trip to Aston Villa next, the wait for a clean sheet may continue.
