Ademola Lookman came off the bench to help Atlético Madrid claim a comfortable 2-0 win over Manchester United at the Metropolitano Stadium, while Barcelona hammered Galatasaray 4-1 in Istanbul on a dramatic UEFA Champions League midweek.

Atlético edge past ten-man United

Pablo Barrios set the tone immediately, finding the net from an Alex Baena assist in the opening minute to hand the hosts an early stranglehold on the contest.

Atlético continued to dominate, though Johnny Cardoso was denied by an offside flag just before half-time. United's evening then took a decisive turn for the worse when Leny Yoro received a red card in the 74th minute, reducing Ruben Amorim's side to ten men.

Lookman, introduced as a substitute for Julián Álvarez three minutes earlier, wasted no time making his mark. The Nigeria international tapped home from close range in the 79th minute to seal the result and register his second goal across all competitions for Diego Simeone's side this season.

Barcelona dismantle Galatasaray in RAMS Park thriller

Across Europe, Victor Osimhen made his first UEFA Champions League appearance of the campaign as Galatasaray hosted Barcelona at RAMS Park — and the occasion quickly turned sour for the Turkish side.

Aleksey Batrakov gave Galatasaray a bright start, scoring in the 28th minute to lift the crowd. Barış Alper Yılmaz appeared to double the lead moments later, only for the effort to be ruled out for offside, leaving the hosts with just a single-goal cushion heading into the break.

Barcelona made the most of the let-off. João Cancelo drew the visitors level two minutes before half-time, and the Catalan giants took full control after the interval. Goals from Fermín López, Anthony Gordon, and Karim Adeyemi completed a commanding 4-1 victory, inflicting a chastening defeat on Galatasaray and leaving Osimhen's Champions League return to forget.
