The 20-year-old has been strongly linked with the likes of Liverpool, Valencia, Malaga, Atletico Madrid and Benfica in recent months.
The youngster’s current contract with Barcelona is set to expire at the end of next season.
Tello has previously admitted he would be interested in a move to Atletico Madrid.
“My dream is to be at Barca, at least for the final year of my contract,” he told TV3.
“It would be a reward for me to go to Atletico. If I have to go, then I will go.”
