Matchday 4 of the Champions League continues this Wednesday with nine matches on the schedule. Iliman Ndiaye and Manchester City travel to Germany to face RB Leipzig (28th, 3 pts). Having struggled in recent weeks, the Citizens (12th, 6 pts) can no longer afford any mistakes and must avoid another poor performance.

Meanwhile, Club Brugge (13th, 6 pts), with Mamadou Diakhon in the lineup, travel to the Netherlands to face PSV Eindhoven (21st, 4 pts). Real Madrid (5th, 9 pts), currently on a seven-game winning streak in all competitions, will be playing away at AEK Athens (27th, 4 pts).

At the Bollaert-Delelis stadium, RC Lens (26th, 3 pts), without the injured Abdallah Sima, host Como (13th, 6 pts). The Italian club will also have to do without their striker Assane Diao, who remains unavailable.

In Istanbul, Liverpool (4th, 9 pts) will host Fenerbahçe (30th, 2 pts). Riding a three-game winning streak, the Reds aim for a fourth consecutive victory to join PSG at the top of the table. In Prague, Arsenal (3rd, 9 pts) travel to face Slavia Prague (32nd, 1 pt). The Gunners are favorites against a Czech side still searching for their first win in the competition.

At Signal Iduna Park, Borussia Dortmund (16th, 6 pts) will try to secure a second consecutive victory against Real Betis (7th, 9 pts). Having lost their previous match against PSV Eindhoven, FC Porto (35th, 0 pts) will be looking to bounce back at home against Napoli (24th, 3 pts).
