The Blues were extremely fortunate not to lose by a heavier margin - we had three goals disallowed by ever-narrowing margins of offside, struck the woodwork twice and Gianluigi Donnarumma was the visitors' star performer.
Yet this was a win based on the solid foundations provided by the defence, with Lisandro Martinez and Harry Maguire at the heart of it.
This was the 40th time they've played together but, crucially, the first time from the outset since the game against Crystal Palace in February 2025.
The Eagles game was the one when Martinez suffered a serious knee injury, and they played as part of a three-man backline with Leny Yoro.
