A couple of surprises here I think are the inclusion of Chadli
he's old, he's been injured for a large part of the past two years and when he's played he was terrible. I'd have taken Saelemaekers over him. Also CB Mechele of Club Brugge always being in the squad and now dropped I didn't expect either, only 5 CB's when you play a 3 CB system is a bit tight imo. Furthermore Witsel might be a gamble too, he almost certainly won't be ready for the group stage, Martinez will count on him for the knockouts but Witsel will not have played a game for 6 months, will he be good to go??
Notible omissions: GK Koen Casteels had a fantastic season for Wolfsburg, but he will miss out because he needs surgery after his final match. Fellaini was rumoured to return but that door is now closed. Divock Origi has really dropped off the map as for as the NT goes and didn't even make the reserves list. Lukebakio from Hertha only had an outside chance to make it and isn't inlcluded either.
