With under 15 minutes to play, it appeared Thomas Tuchel's Madrid miracle was actually going to happen. Timo Werner's mazy solo run had unravelled Carlo Ancelotti's already rocked defence to give Chelsea a 3-0 lead.
Then Tuchel opted to take the confident Werner off for Christian Pulisic to add fresh legs to Chelsea's intense attack. The move altered the game, with the American missing two guilt-edged chances in added time after Rodrygo had levelled the tie on aggregate.
Pulisic's display was disappointing, losing the ball too easily and failing to offer the same dynamic movement the German had before coming off.
