Reports emerged last week that Atletico Madrid could be set to sell Saul Niguez this summer, and several top Premier League clubs are interested.
In order to sign the Spanish midfielder however, Chelsea will have to pay a huge fee, which is something that they are unsure of doing especially when it comes to a midfielder given their depth in central midfield.
Chelsea are targeting a starting striker that could end up costing them over £100 million (€116 million), and so if they do sign a midfielder as well, they will have to splash plenty of money this summer.
Atletico Madrid want around £68.8 million (€80 million) for Saul, even though they claimed that they would 'welcome the sale' of the midfielder this summer.
There have been several reports of players set to leave Chelsea this summer, with the likes of Fikayo Tomori, Hakim Ziyech, Ross Barkley and Emerson Palmieri all being linked with moves away, with this helping to raise funds for potential incoming transfers.
The report adds that the likes of Bayern Munich, Juventus and Paris Saint-Germain have all shown an interest in the Spanish midfielder recently, and so if Chelsea want to sign Saul, they will have to move quickly.
Saul is currently under contract until 2026 with Atletico Madrid, and so the La Liga champions are in a strong position to negotiate a transfer fee.
The 26-year-old has been one of Atletico Madrid's most important players over the last few years, yet he has had a reduced role in the team this season, as while he has made 41 appearances in all competitions, only 22 of them were La Liga starts, with fellow Spanish midfielder Marcos Llorente playing a more important role in the midfield.
