Matthijs de Ligt's move to Barcelona at the end of the season is stalling as a result of the fee his agent Mino Raiola is demanding from the Catalan club.
The 19-year-old is European football's hottest defensive prospect and has been heavily linked with a number of top clubs ahead of the summer transfer window, with Barcelona believed to be at the front of the queue after already snapping up his teammate Frenkie de Jong.
But Marca report the deal for De Ligt is being held up as a result of his agent Raiola, who is demanding a €14m commission as part of the agreed €70m transfer fee between Ajax and Barcelona.
