Don't know if it's been mentionned, but xG on this game were 0,6 for Lyon, and 2 for Barca. Yet, I feel the 2 most impressive saves were made by MATS (on Aouar and Terrier), not by Lopes. It's because Lyon's biggest opportunities were long range shot (or, well, medium range maybe for Aouar, right outside the box). Barca had HUGE opportunities that didn't even end on target (notably by Suarez - which isn't surprising considering his current form), and Messi - which is more unlikely). Read somewhere 25 shots, only 5 on target for Barca, that's absolutely crazy low, especially when some of those shots were rather easy, it's not like everybody tried to score from 30 meters or something.
I feel that overall, the 1st half was poor technically, even though there's been a couple of chances, there were just too many dumb defensive mistakes by both teams. Second half was a bit better, with Barca controlling the game and getting some very big opportunities. Lyon is not an easy team when they're really focused. City didn't dominate the game at all. Barca did, at least for the second half. It all came down to a couple great performances by Lopes, Denayer and Dubois (who's a really interesting RB by the way), and some very clumsy finishing by Suarez (and the rest).
Second leg should be interesting, as Fekir should help Lyon quite a bit. I mean, yeah, Arthur will probably be back too. But Barca didn't need Arthur to control the game during the second half. Lyon struggled to create chances, and that's something that Fekir can do, much much better than Depay or Traore. Plus, Ndombele should be fitter, and hopefully Mendy won't get injured during warm up this time. I don't expect Lyon to go through though, and I think Barca will win 3-1, but the game itself could be funnier to watch than this first leg.
