Transfer talk surrounding Marc Guiu is intensifying, with reports suggesting Real Betis are monitoring the Chelsea forward closely. The player has caught the attention of several scouts as other clubs prepare for a potentially active transfer window. Until a fee and conditions are finalised, the deal remains vulnerable to disruption - especially if Sunderland and Chelsea decide to make a formal offer of their own in the coming days. At 1.62 goals scored per game this season, Real Betis already pose a big threat. Marc Guiu would be expected to maintain that level and give them another reliable option in attack. Chelsea have recently been linked with Castello Lukeba, Santiago Thomas Castro and Strahinja Pavlovic while Real Betis have had no rumoured targets. Want more transfer rumours like this?
