Anthony Taylor refereed a tasty London derby really well, getting his involvement just right.
Kyle Walker flew into Manuel Lanzini after just 12 minutes to pick up the game’s first yellow card and was outdone by Mark Noble three minutes late.
Both tackles were strong but only worthy of cautions.
The biggest moment of the first half, though, came when Hugo Lloris raced out of his penalty area and cleaned out Lanzini, ball and anything else that was coming through.
