It's bad enough some posters are giving 4 answers but can you clarify that you mean non-HG players and maybe edit your OP?Back in the late 80s and early 90s, pre Bosman ruling, Italian clubs could have a maximum of three non-Italian players in their squad.
If that was currently in place in the Prem which three Spurs players would you keep?
It's a tough one when you think about players in their prime, players at the later stages of their career, and exciting young talent like Sarr and Udogie.
