Glasgow Celtic and Glasgow Rangers, both are famous clubs.
You need to add a list of players to your question, or it doesn't make sense.
Obviuos answers are the Italians Paulo di Canio and Massimo Donati, others are Paul Elliott who played for Bari and Shunsuke Nakamura who played for Reggina. There are probably more but cant think of any
Both Celtic and Glasgow Rangers play in the Scottish league.
mo johnstone,mark brown and Kenny miller. Kenny miller is the only player to have played for rangers then to Celtic and now back at rangers
"I think it was Ronald De Boer after he left Barcelona." Not the case - both Ronald and Frank played for Rangers, not Celtic. No Dutch players have played for both - Rangers were linked with ex-Celt Pierre Van Hooijdonk when Dick Advocaat was in charge, Celtic were linked with Giovanni Van Bronckhorst before he left Arsenal. Neither came about.
Gretna used to play in England till it got entered into the scottish football league, where it went bust. Berwick Rangers are on the England/Scotland border but play in Scotland.
