Arsenal will face Atletico Madrid over two legs for a place in this season’s Champions League final.

Havertz’s stoppage-time winner from the opening match proved enough for an unconvincing Arsenal.

The Gunners’ season is in danger of falling apart after a third domestic defeat in a row.

Substitute Kai Havertz struck in injury time to put Arsenal on course for the semi-finals.

The last-eight rubber looked to be heading for a goalless draw before Havertz latched on to Gabriel Martinelli’s ball to deliver a fine finish.

The England international was absent for his side’s shock FA Cup demise at Southampton on Saturday.
