Manchester City, on Tuesday night, overcame an early scare to get their UEFA Champions League defence off to a solid start, defeating Red Star Belgrade 3-1 at Etihad Stadium.

Barcelona cruised past Antwerp while France forward, Kylian Mbappe, helped Paris-Saint Germain (PSG) to an opening win on a breathless beginning to the group stage of Europe’s top club competition.

Newcastle returned to Champions League for the first time in two decades with a battling goalless draw against AC Milan at the San Siro and Lazio grabbed an equaliser deep in injury time to hold Atletico Madrid.

In Manchester, Pep Guardiola’s City were stunned when Red Star’s Osman Bukari opened the scoring in first-half stoppage time.

But Julian Alvarez continued his sparkling early season form by levelling just two minutes after the break.

The Argentine then got some help from Red Star goalkeeper, Omri Glazer, as he flapped at Alvarez’s free-kick to allow the ball to fly into the far corner.

Rodri rounded off a 3-1 win with a composed finish 17 minutes from time.
