A number of Premier League clubs are reportedly tracking Osasuna striker Ibrahima Balde.
The 23-year-old scored seven times in La Liga last season following a move from Atletico Madrid.
Aston Villa, Norwich City, Reading and Sunderland are now all thought to be interested in signing the Senegalese forward, according to Sky Sports News.
Balde, who has two years left on his current contract, is thought to have a £7m buy-out clause.
