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.
5. Cameroon
Michel Pensee Bilong will be remembered fondly for his defensive performances during the 2004/05 season, but those back in his native Cameroon will also remember him as part of the African Cup of Nations winning side in 2000 Photo: Ben Radford
6. Peru
Cristian Benavente will arguably be remembered as one of Dons' worst signings after signing from Real Madrid B in 2015, amassing just five appearances before being cut loose. His Peru career though has seen him represent his career 18 times, scoring twice. Photo: ERNESTO BENAVIDES
7. Republic or Ireland
Troy Parrott was a star man for MK Dons in the second-half of last season, and is already a regular for the Republic of Ireland. He is not the first MK Dons player to represent Ireland though, with Stephen Quinn taking that honour, while Keith Andrews and Stephen Gleeson all pulled on the shirt. Photo: Oisin Keniry
8. Congo
Benik Afobe has gone from strength-to-strength since his loan spell at MK Dons. Big money moves followed, as well as a call-up to the Congo squad. He has made six appearances and scored one goal. Photo: Pete Norton
