Atletico Madrid and Barcelona are reportedly struggling to come to an agreement for the transfer of Luciano Vietto.
It had been claimed that Barcelona had agreed a price in the region of £18m with the capital outfit, which would see the forward make the move to Camp Nou this summer.
However, according to AS, there is no such an agreement in place and the deal is threatening to collapse as Atletico are refusing to drop their asking price for the Argentine.
The 22-year-old earned himself a move to Atletico last summer after hitting 20 goals in 48 appearances during an impressive first season in Spanish football with Villarreal.
Vietto, who scored in Atletico's pre-season win over Numancia on Saturday night, only managed three goals for the capital club during the 2015-16 season, however, and it is understood that Diego Simeone is open to a sale this summer.
