Porto have opened talks with Utrecht over the potential transfer of Souffian El Karouani, who currently plays as a defender. According to multiple reliable reports, negotiations are active and ongoing after an opening bid was submitted, though there is reportedly still some distance between the clubs on valuation. However, discussions are said to remain open and constructive - as both sides explore whether there is a deal to be done. Frankfurt, Fenerbahce and West Ham have not withdrawn their interest and could still influence the outcome. Porto's back line has been a real strength this season, conceding just 0.27 goals per game (4 in 15). Souffian El Karouani would be expected to slot into that unit and hold his own in an already solid setup. Speculation continues to connect Porto with Thiago Silva while no fresh rumours surround Utrecht. Looking for Porto transfer rumours?
