Poyet has been one of Charlton's shining lights this season and caught the eye during their run to the quarter-finals of the FA Cup.
The 18-year-old, who is the son of Sunderland boss Gus, has been highly-regarded at Charlton for some time and he has established himself in the first team this season.
Poyet's potential has not gone unnoticed higher up the football pyramid with the likes Tottenham, West Ham and Fulham all keeping tabs on his progress.
The Spanish born-teenager is also thought to have admirers on the continent with Barcelona seeing him as a potential star of the future they can groom at Barcelona B, while Italian giants Inter Milan are also monitoring his situation at the Valley.
The England youth international is out of contract at the end of the season and Poyet's suitors are waiting in the wings to snap up him in the summer.
