Cristian Tello joins Porto on loan

Barcelona have sanctioned the loan departure of Cristian Tello to Porto.

Under the terms of the deal, the Spanish winger will spend the next two seasons with the Portuguese club, who have the option to make the move a permanent one.

However, Barca retain the right to cancel the agreement after one campaign, which would see the 22-year-old return to the Camp Nou.

Tello made 30 appearances for the Catalan outfit last term, during which he scored five goals.
