Celtic boss Brendan Rodgers is ‘desperate’ to sign a long-term replacement for Mikael Lustig and he is keen to sign the exciting young Portuguese defender.

Fonseca hasn’t played for Porto’s senior side this season. He has played only for the B team. Porto are looking to do business with the Hoops over Fonseca and the player is equally keen to move.
