Leicester are closing in on midfielder Adrien Silva and are also keen on bringing his team-mate Islam Slimani to the King Power Stadium.
The deal for the pair would cost in the region of £50million and The Guardian believe the Foxes are ready to make a big statement before they embark on their Champions League adventure.
The arrival of Silva in particular appears to be imminent after he revealed in an interview with Portuguese newspaper O Jogo that he is ready for a new challenge with the Premier League champions.
“Yes, I confirm this proposal,” Silva said. “Leicester is very interesting and corresponds to my career goals.
“After the past 15 years at Sporting, this opportunity is something exceptional for me and can allow me to express and impose myself in another championship, and also to evolve in the Premier League, which is a stunning league. I love Sporting as a family and I dedicated myself to the club since I was 12 years old.
“With Sporting I lived many moments of happiness. I can say that I grew up with the club. At 27 years old, and after so many years of loyalty, I think that no one will criticise me for wanting to embrace this challenge.”
However, Sporting Lisbon are defiant in their response to Silva’s claims.
A statement read: “The player renewed his contract in February 2016 in a deal involving significant sums of money, making it absolutely clear that the extension to his contract would mean that Adrien Silva would say at the club until the end of his career.
“Never during recent months has anything been said to the president or has any proposal been made for the transfer of Adrien Silva and the president has not met with the player’s father or representatives for that purpose.
“Sporting CP and its president will always defend the interests of the club and will also defend the club’s assets.”
If the £21million deal is wrapped up for the Euro 2016 winner, Leicester will return to Sporting for Slimani after already seeing a £25million bid rejected earlier in the summer.
The Portuguese club are said to be holding out for £30million which means other reported suitors such as West Brom will also have to up their opening offer.
