Baldock, now at Sheffield United, took the call last week to join up with the Greek squad for the first time after an impressive season in the Championship.
Here is a look at some of the nations to have been represented by MK Dons players past and present.

Dons' biggest export Dele Alli almost went straight into the England squad after leaving Stadium MK in 2015, racking up 38 appearances for the Three Lions. Alan Smith also represented his country prior to moving to MK Dons, while former loanees Jake Livermore and Andros Townsend have also pulled on the England shirt during their careers.
