Paul Pogba's move from Juventus to Manchester United is stalling over a stand-off regarding who pays his agent's fee, according to reports.
The France midfielder is understood to be in advanced talks with United about a return to Old Trafford, four years after he left Manchester to play in Serie A.
While agreement on his personal terms has been reached, neither club seems willing to pay the €20m (£16.8m) fee Pogba's agent Mino Raiola wants for brokering the deal, according to Sky Sport Italia.
New Red Devils boss Jose Mourinho has already signed three players this summer - Eric Bailly from Villarreal, free agent Zlatan Ibrahimovic, and Borussia Dortmund midfielder Henrikh Mkhitaryan.
