Transfer interest is building around Caleb Marfo Yirenkyi, with Porto understood to be weighing-up a move for the Nordsjaelland midfielder. While there has been no official bid as yet, the club may act swiftly if they decide to pursue the deal before the transfer window slams shut. While Porto and Nordsjaelland continue talks, no breakthrough has been reported. Chelsea, Arsenal and Liverpool reportedly may still have an interest, but currently the focus is on getting this deal across the line. So far this season, Porto are steady at both ends (1.97 goals scored per game, 0.55 goals conceded per game). The role for Caleb Marfo Yirenkyi would be to keep that balance while lifting performances across the pitch. Reports suggest Porto are monitoring Andre Silva whereas Nordsjaelland have not been associated with other players at this stage. Looking for Porto transfer rumours?
