From winger perspectives? Tons. Ball progression, ball retention, track back, pressing. If you want to be final 3rd guy, you expect double digit number at least.
It is pretty much the same with striker, some striker when he is not scoring he is useless aka Michy, other striker when he is not scoring his contribution to the team is still plenty aka Giroud.
Not sure there is anyone that really standout but Kovacic will win it. I thought Tammy in the beginning but he has been out of form for a while now.
