Olexandr Zinchenko, currently with Arsenal, is the latest name linked with a potential switch to Porto. The defender could become a key signing should the move materialise, as the club seeks to strengthen in a key area of the pitch. Porto have laid out their intentions, but valuation and timing remain under debate. Nottingham Forest, Marseille and Real Betis are keeping tabs in case talks collapse or progress slows further. With only 1 goals conceded in 8 (0.12 per game), Porto have been one of the stronger defences in the Primeira Liga this season.. Olexandr Zinchenko would be asked to keep that standard and provide dependable cover when needed. Arsenal have recently been linked with Anthony Gordon, Benjamin Henrichs and Marc Guehi while Porto have had no rumoured targets. More on this story as it develops. Need more Porto transfer rumours?
