Dier will have to work very hard to earn further playing time under Conte. At fault for both goals. Gets out-thought and out-fought for the first, nutmegged on the second. For being such a big guy, he plays small.
Romero's second yellow was a complete screw-up by him. He had three other defenders behind him. No need to panic and tackle the Vitesse guy. Just turn and run with him to minimize his time and space on the ball. We're seeing a guy still not fully adjusted to his backline team mates and making rash decisions. He's a good player but Conte will need to focus on making him play smarter.
Hojbjerg was curiously inept moving the ball forward. We see him stroking passes with precision for Denmark yet he misses on line and length far too often when playing with Spurs. He's got hospital pass written all over him and needs to be sorted before he gets one of our attacking players injured.
I was pretty happy with Kane, Reguilon, Emerson and Son. And Lloris, who had to be sharp on some well-directed shots.
