Chelsea have joined the race to sign Manchester United and Arsenal target William Carvalho after sending scouts to watch the midfielder in action during Sporting Lisbon's 1-1 Primeira Liga draw with Academica on Saturday.
The Daily Mirror cites a report in Portuguese newspaper O Jogo, suggesting that the Blues are now possible challengers for the 22-year-old's signature, despite the fact he was sent off in front of his Premier League suitors.
Jose Mourinho is believed to be on the lookout for further reinforcements at Stamford Bridge despite previously insisting that Chelsea's transfer business was over in the current summer window.
The acquisition of Diego Costa, Cesc Fabregas, Filipe Luis and Didier Drogba has significantly strengthened the Portuguese coach's first-team squad for the 2014/15 campaign, and is sure to place the west London club in contention for the Premier League title this season.
Chelsea are set to kick-off their opening match at home to newly promoted Burnley on Monday evening, and will be looking for a winning start against Sean Dyche's side following victories for title rivals Arsenal, Liverpool and Manchester City over the weekend.
The Gunners were made to work hard for their three points against Crystal Palace, claiming a 2-1 win at the Emirates Stadium thanks to a last minute strike from Aaron Ramsey.
Arsene Wenger has had a very successful summer recruitment drive in north London, with Alexis Sanchez, Mathieu Debuchy and Calum Chambers all impressing on their competitive Arsenal debuts.
The Frenchman is still reportedly in the market for a holding midfielder though, and Carvalho could be the man lined up for a move before the transfer deadline on September 1.
Man United interest
Manchester United complete the trio of Premier League contenders for Carvalho's signature with Louis van Gaal also known to be on the lookout for a defensive minded player to protect his back line at Old Trafford.
After a disastrous 2-1 opening day defeat at the hands of Swansea City, the Red Devils boss is likely to press ahead with plans for a late recruitment drive.
The €30 million valuation is unlikely to be a sticking point for any of the player's admirers after Sporting climbed down from insisting suitors meet €45 million buyout clause. It just remains to be seen the eventual destination where the in-demand star ends up.
