Are you serious? Let us break it down (Not taking every player):
Lloris, Gomes, Friedel,
Walker, Rose, Verthongen, Kaboul, Dawson, Naughton, Chiriches
Lennon, Paulinho, Lamella, Capoue, Sigurdson, Chadlii, Eriksen, Townsend, Dembele, Sandro, Bentaleb
Adebayor, Soldado, Kane
Some young english players emerging with Pochettinho helping them. But look at the rest. Team I would say is full of internationals and really good players. Pretty much everyone played for their national team. Pochettino didn't came to some random team. He then started buying and selling players so they could play in his system. But as I said, he came to a very good team.
