Champions League record Jose Mourinho helped set could be broken by Arsenal and Man City

Arsenal and Manchester City are on the brink of making Champions League history, a record that Jose Mourinho had a hand in setting. By Wednesday night's end, the semi-final line-up will be complete, potentially with a historic twist.

Paris Saint-Germain and Borussia Dortmund have already secured their spots in the semi-finals following their respective quarter-final victories. Both second legs were nail-biters, with PSG overcoming Barcelona 4-1 on the night, and 6-4 on aggregate.

Barcelona entered the second leg at Camp Nou with an advantage after a 3-2 victory in Paris last week. However, goals from Ousmane Dembele, Vitinha and a double from Kylian Mbappe saw Xavi's side exit the competition.

Meanwhile, Bundesliga giants Dortmund triumphed 4-2 over Atletico Madrid, advancing to the semi-finals with a 5-4 aggregate win. Edin Terzic's team looked set for elimination in the 70th minute, but late goals from Niclas Fullkrug and Marcel Sabitzer turned the tide.

The remaining quarter-final matches will take place on Wednesday night, with Arsenal facing Bayern Munich away and Manchester City hosting Real Madrid at the Etihad. Both ties hang in the balance after captivating first-leg encounters.

The Gunners secured a 2-2 draw against Thomas Tuchel's squad at the Emirates, in a match that saw the lead change hands multiple times. Similarly, Pep Guardiola's team led twice at the Santiago Bernabeu, only to end up with a 3-3 draw against Los Blancos.
