CHELSEA are battling against the clock to swoop for Benfica wonderkid Joao Felix.
The 18-year-old attacking midfielder is being eyed by Blues boss Maurizio Sarri after an impressive start to the season.
He has scored twice in eight appearances for Benfica so the Portuguese giants are eager to tie him down to a fresh deal.
Felix, who has represented Portugal at Under-21 level, is currently under contract until the summer of 2022.
Under the terms of his deal, Felix can be signed by activating a £45m buy-out clause.
However, Benfica want to significantly increase the value of his transfer fee to £105m.
The fresh contract would also add an extra season to his spell at the Estadio da Luz.
According to the Sunday Mirror, Felix could agree the new contract by tomorrow unless Chelsea firm up their interest.
If he does strike an agreement with Benfica then Felix would be out of Chelsea’s price range.
West Ham attempted to sign the promising talent in the summer transfer window.
Clubs in Italy and Spain are also reportedly monitoring his progress.
Chelsea made four signings in the summer after recruiting Sarri to succeed Antonio Conte as boss.
Kepa Arrizabalaga arrived from Athletic Bilbao for a world-record fee for a goalkeeper while Jorginho was snapped up from Sarri’s former club Napoli for around £50m.
Mateo Kovacic joined from Real Madrid on loan while veteran goalkeeper Rob Green completed a freebie deal to provide back-up.
Chelsea have enjoyed an unbeaten start to life under Sarri.
They are currently third in the Premier League table, top their Europa League group and are in the last eight of the Carabao Cup.
Next up is a home clash against London rivals Crystal Palace this afternoon (4pm).
