Chelsea have reportedly added Rayan Fofana to their shortlist of transfer targets. The Lens forward is rumoured to be attracting attention ahead of the next transfer window, with insiders claiming preliminary talks could soon take place. Until a fee and conditions are finalised, the deal remains vulnerable to disruption - especially if Arsenal decide to make a formal offer of their own in the coming days. Chelsea have been strong going forward this season, with 48 goals scored in 27 games (1.78 per game). Rayan Fofana would give them depth and keep that attacking firepower going all season. Reports suggest Chelsea are monitoring Ousmane Dembele, Lucas Bergvall and Igor Thiago Nascimento Rodrigues whereas Lens have not been associated with other players at this stage.
