Bernardo Silva and RB Leipzig's Dani Olmo both reportedly have 'Barcelona clauses' in their contracts to ease a move to the Catalan giants should they wish to go.
After signing contract extensions with their current clubs this summer, the two reportedly have 'affordable termination clauses' in place should Xavi's team come hunting for them.
Silva signed a new contract with City until 2026 in August, with officials keen to fend off interest from the Spanish side.
Barca president Joan Laporta admitted he wanted the City star in the summer and it was reported that the midfielder would try and force through a move if they came in for him.
