Probably because he got beaten the 2-3 times he got a clear run at him and set up opportunities. Despite that, if you consider that James, Trippier or TAA had been playing, he'd have been 5 yards ahead of them, as opposed to 1 yard Him and Dembele were managed so well though, midfield and wingers were all over them.
Saka going off for Sterling was awful. I'm sure you've been frustrated by this before at City, but there was a point in the last minute where he could have played a pass into the box but he took a touch and passed it back.
You say France have been rubbish, but internationals aren't as finely tuned as club games. Sounds bitter af.
