The transfer mill is churning once again, with Newcastle believed to be lining up a move for Rico Lewis, the defender from Manchester City . Sources close to the club suggest they are exploring options to reinforce their squad ahead of the run-in. Newcastle are still pushing to finalise terms. However, Tottenham, Chelsea and Nottingham Forest are still watching closely and may return with offers of their own. Newcastle's back line has been a real strength this season, conceding just 0.71 goals per game (5 in 7). Rico Lewis would be expected to slot into that unit and hold his own in an already solid setup. Manchester City continue to be linked with Senny Mayulu, Valentino Livramento and Denzel Dumfries while Newcastle are also rumoured to be tracking Adam Wharton, Dani Vivian and Marc Casado Torras.
