Transfer talk surrounding Fermin Lopez Marin is intensifying, with reports suggesting Sunderland are monitoring the Barcelona midfielder closely. The player has caught the attention of several scouts as other clubs prepare for a potentially active transfer window. Newcastle, Chelsea and Man Utd have not withdrawn their interest and could still influence the outcome. So far this season, Sunderland are steady at both ends (1.27 goals scored per game, 0.91 goals conceded per game). The role for Fermin Lopez Marin would be to keep that balance while lifting performances across the pitch. Barcelona have recently been linked with Ryan Gravenberch, Victor Osimhen and Scott McTominay while Sunderland have had no rumoured targets. Need more Sunderland transfer rumours?
