Ernesto Valverde has already started thinking about bolstering his back line for when the transfer window reopens in the new year.
He has turned his attention to De Ligt, who according to the Spanish media outlet, has potential 'unparalleled by other defenders his age.'
After scoring on his senior debut for Ajax last September, he was given his first senior international cap with Holland back in March despite having only played two league matches for Ajax.
The young talent's current deal with the Dutch club expires in 2021, but Barcelona are reportedly confident of getting a winter deal over the line.
