Chelsea are ready to make an offer for Porto forward Jackson Martinez, according to the Metro.
Reports suggest that Martinez will be the first port of call should Mourinho's third effort to sign Wayne Rooney prove unsuccessful.
Chelsea have confirmed they will not make an offer for Rooney until after their clash with Manchester United on Monday but regardless, David Moyes remains adamant that the striker remains firmly in his plans at Old Trafford this season.
If a third bid for the former Everton striker should be turned down then Mourinho will move on to his much talked about 'plan B', which is widely considered to be the capture of Martinez.
The Porto striker was in scintillating form last season, and is being closely followed by Napoli as well, though his club are determined to hold out until his £30million release clause is met.
The 28-year-old netted 29 times in 38 appearances for Porto last term, and could provide the attacking pedigree Mourinho is so desperately seeking.
