The Daily Mail reports that Premier League clubs Swansea City and Leicester City are interested in Brentford midfielder Jota.
The 23-year-old has scored 11 goals from midfield this season for the Bees and has helped the club to reach the Premier League promotion play-offs.
The Spaniard, who is also a reported target for promoted AFC Bournemouth, was signed from Celta Vigo last summer for a fee believed to be around £1million.
While on loan, he helped Eibar to achieve promotion to the La Liga last season and was voted best-attacking midfielder of the season in Spain's second division.
