Real Betis holds out for £ 35 million while Chelsea is interested in a highly valued winger Jesus Rodriguez.
Mail Sport reported earlier this year that an increasing number of elite European clubs have taken note of the performances of the 19-year-old in what his outbreak season has been in La Liga.
Lightning Quick, the Spanish U19 International, has become a favorite of the public with his work ethics and the willingness to accept opposition distributions.
Coach Manuel Pellegrini used him as a left wing player who cuts his right foot while he also thought on the other side, to replace Antony on loan from Manchester United.
Chelsea has already bought Geovany Quenda from Sporting Lisbon, but he will stay in Portugal in Portugal next season.
However, the Stamford Bridge side did not stop adding more young talent if they want to strengthen their attack.
Jadon Sancho initially seems to return to Manchester United in the summer and they investigate options that can strengthen their attack.
Rodriguez could even be purchased and read back, but his status and athletics make him an ideal prospect for the Premier League.
He won the European U19 championship with Spain last summer and only made his first team debut for Betis in October, but has since made a strong impression in his 22 performances.
Co-owner of Manchester United Sir Jim Ratcliffe spent Antony and Sancho as two of the six Red Devils stars who 'did not pay well enough and too much last month'.
Rasmus Hojlund, Lisandro Martinez, Andre Onana and Casemiro, who are still still in the club in contrast to Antony and Sancho, were the other four players who were called by the Ineos owner, while in recent years he had the club's overbidings on the club's utensils.
“This summer we will” buy “, we will” buy “Sancho, we will buy” Casemiro “, we will” buy Martinez “, we will” buy Hojlund “, we will” buy “it, and they will all be around £ 17 million,” said Ratcliffe in March.
'If we don't buy anyone, we buy those players. It is not a light switch (which can be switched off). These are all things from the past, whether we like it or not, we have inherited those things and have to look it up.
'For Sancho, who now plays for Chelsea and we pay half of his wages, we pay £ 17 million to buy it in the summer.
'Some are not good enough and some are probably paid too much, but for us to form the team for which we are fully responsible and are responsible, will take time.
'It takes us time to go to a new place in the future of the past. We have this period of transformation where we will go from the past to the future.
'There are some great players in the team as we know, the captain is a fantastic football player. We absolutely need Bruno (Fernandes), he is a fantastic football player. '
