Don't forget David Luiz, he pinged some super passes out there (even if he did his usual 20 touches then terrible throghball attempt 'trick' too many times).
Agree that Tierney and Smith Rowe were really imressive, but then they pretty much always are. I personally really like the latter off the left, I think it suits him a lot and takes a little of the creative pressure off from him.
I also think, if you give Saka a proper right back to work with, he's capable of working in tandem to do similar damage to opponents' left sides. The three of them are incredibly smart footballers, at the same time with great athleticism and technique - a mixture we have not had often in our players in the past 15 years.
