The transfer mill is churning once again, with Napoli believed to be lining up a move for Martinez Arnau, the defender from Girona. Sources close to the club suggest they are exploring options to reinforce their squad ahead of the run-in. While Napoli and Girona continue talks, no breakthrough has been reported. Crystal Palace reportedly may still have an interest, but currently the focus is on getting this deal across the line. With only 5 goals conceded in 5 (1.0 per game), Napoli have been one of the stronger defences in the Serie A this season.. Martinez Arnau would be asked to keep that standard and provide dependable cover when needed. Reports suggest Napoli are monitoring Raheem Sterling, Jadon Sancho and Ademola Lookman whereas Girona have not been associated with other players at this stage. Looking for Napoli transfer rumours?
