Chelsea are weighing up expanding their Czech Republic contingent with the signing of teenage attacking midfielder Dominik Masek.
Masek is currently tied to FK Pribram, but has already turned out for Chelsea's youth team this season.
The midfielder played for the Czech Republic in last summer's U17 World Cup and trained with the Blues academy last season along with FK Pribram teammate Vaclav Cerny, who is also on Chelsea's wanted list.
Chelsea already have Czech Republic goalkeeper Petr Cech and defender Tomas Kalas on their books.
