Yes, I will concede that Chelsea had one glorious chance on goal for the game when Husdon-Odoi got through early on, De Gea has to earn credit for the brilliant foot save. But for the save, the ball was going in, not wide right.
As Rudiger, he didn't have time for a second touch. Had that same ball fallen for prime Ronaldo you could say the ball should have resulted in a goal, but Rudiger is no prime Ronaldo in the opposition box. It would be unreasonable to suggest that Rudiger should have scored from there.
Going into the game, no one would have expected us to keep Chelsea down to one glorious chance. In fact, I can't think of any side on the planet who you'd say would be expected to keep a clean sheet in open play against this very good Chelsea side. But that's exactly what we did. Chelsea had lots of half-chances -- the two Rudiger chances, the Werner chance -- but only one chance where you'd say Chelsea should have scored. But it's not as though Hudson-Odoi fluffed the chance. De Gea made an outstanding save, and an outstanding save is as important or as much a part of defending, as majestic CB or FB play.
