In a thrilling Champions League opener, Atletico Madrid snatched victory from the jaws of defeat, thanks to Jose Maria Gimenez's 90th-minute header against RB Leipzig.

The German visitors drew first blood through Benjamin Sesko's fourth-minute header, catching Atletico off guard.

However, Antoine Griezmann, Atletico's talismanic forward, restored parity with a stunning 28th-minute volley, his 37th Champions League goal. Griezmann's brilliance continued throughout the match, with a spectacular save from Peter Gulacsi denying him a second goal.

As the clock ticked toward full-time, Griezmann orchestrated the winning moment, delivering an pinpoint cross that Gimenez expertly headed home.

Conor Gallagher, Atletico's £33m summer signing from England, made his Champions League debut for the club in the 63rd minute, replacing fellow midfielder Geoffrey Kondogbia. Gallagher followed in the footsteps of Kieran Trippier as the second English player to feature for Atletico in the competition.

The dramatic victory sets Atletico up for their next challenge against Benfica on October 2, while RB Leipzig seeks redemption against Juventus on the same date.
