Currently the Blues are going to be suspended from making signings for the next two windows but they still believe this could be frozen.
This means they are continuing with their recruitment plans for the summer with Neres now at the top of their list.
Luka Jovic had previously been their No.1 target with the Blues keeping a close eye on his form for Eintracht Frankfurt this season.
The ex-Benfica man, though, is now set to join Real Madrid after 27 goals in 47 appearances, including two in two games against the Blues in the Europa League.
But now, according to the Press Association, Neres is the man Chelsea want to purchase to bolster their squad.
