According to multiple reports, Barcelona are in formal negotiations with Porto over the signing of Jakub Kiwior. The defender has been a target for some time, and talks are said to be intensifying as the window progresses. The player remains under contract, but movement looks increasingly likely the longer talks go on. Crystal Palace, Juventus and Porto are reportedly waiting in the wings. Finalising a fee and payment terms remains central to closing the transfer. With only 32 goals conceded in 36 (0.89 per game), Barcelona have been one of the stronger defences in the LaLiga this season.. Jakub Kiwior would be asked to keep that standard and provide dependable cover when needed. Reports suggest Barcelona are monitoring Levi Colwill, Rafael Leao and Joao Pedro whereas Porto have not been associated with other players at this stage. Need more Barcelona transfer rumours?
