Ansu Fati had appeared set to leave Barcelona for Monaco in the summer transfer window but doubts are starting to appear about the transfer.
A deal between the three parties has still not been agreed despite recent reports claiming it was close to being finalized.
According to Diario Sport, Monaco are starting to get frustrated about the lack of process as they aim to bolster their squad this summer.
