The transfer mill is churning once again, with Chelsea believed to be lining up a move for Kees Smit, the midfielder from AZ Alkmaar. Sources close to the club suggest they are exploring options to reinforce their squad ahead of the run-in. Chelsea are still pushing to finalise terms. However, Tottenham, Real Madrid and Man Utd are still watching closely and may return with offers of their own. So far this season, Chelsea are steady at both ends (2.0 goals scored per game, 1.12 goals conceded per game). The role for Kees Smit would be to keep that balance while lifting performances across the pitch. Reports suggest Chelsea are monitoring Fisnik Asllani, Marc-Andre ter Stegen and Dayot Upamecano whereas AZ Alkmaar have not been associated with other players at this stage.
