Barcelona are worried about Manchester United’s interest for Samuel Umtiti.
The defender’s form and €60m buyout clause is attracting United ahead of the January market.
Marca says United boss Jose Mourinho has been enticed by this figure, but he is concerned that he may not get the funds to boost his squad in the New Year.
The Spanish giants are wary of losing the defender during the next transfer window.
The 23-year-old is one of the lowest paid players in the squad despite starting nine of Barca’s XI La Liga fixtures this term.
