William Saliba returns to French soil with a point to prove. After an uncharacteristic error against Crystal Palace midweek, Saliba will need to shake off any doubts quickly. His Champions League numbers, though, tell a reassuring story: five clean sheets in seven appearances. Without Gabriel beside him, Saliba’s task becomes even more important. Facing a PSG attack loaded with speed and flair, including an in-form Ousmane Dembele, Saliba must stay composed. His ability to read the game early, step into passing lanes, and dominate aerial battles could define whether Arsenal survive the night or get overwhelmed.
