Benfica face losing England U18 striker Jeremy Sarmiento.
The Sun says the 17 year-old has one more year left on his contract with the Portuguese giants.
The former Charlton rookie moved to Portugal from the Addicks in 2018.
He was previously linked to Manchester City, before heading to Lisbon to continue his football education.
Born in Madrid to Ecuadorian parents, Sarmiento also has a decision to make about his international future.
The lightning-quick starlet is at the centre of a tug-of-war between England, Spain and Ecuador, who all believe Sarmiento has the potential to play for them.
Forward Sarmiento moved to Benfica in 2018 and has excelled. The wideman, likened to Borussia Dortmund sensation Jadon Sancho, has already played for Ecuador's U15 side.
