1st goal- Bought Byram out of position with a top-speed run, creating space for De Bruyne to arrive unmarked and finish. This was absolutely deliberate and he knew exactly what he was doing, having decided from the instant Cresswell's loose pass left his foot.
2nd goal- Makes a good run onto De Bruyne's ball, nutmegs Sam Byram after initially feinting away from him, pushes it past Fonte knowing that a 33-year-old centre-back can do absolutely nothing to stop him, then has the awareness and selflessness to square it across goal rather than shooting.
3rd goal- Spots the opportunity to make an interception before the pass had even left the opponent's boot, nicks it with the speed only he possesses and plays a brilliant early pass into the path of Sterling.
Navas when he arrived was quick. Sterling is very quick. Adama Traoré, Hector Bellerín, Theo Walcott... all quite quick.
I would argue that Sané's quicker than all of them, and last night he displayed the technique and intelligence to go with it.
