France have called up Sissoko ahead of Ndombele despite former having 25 appearances for Spurs this year and latter having 33.

Spain have called up more Brighton players than Real Madrid players (Ramos is dropped) despite latter making it to the Champions League semi-final.

It's not necessarily the 26 best players in the country and this year more than ever (due to disrupted football calendar) several teams are looking favourably at players with experience in the system.
