The new contract for Newcastle United midfielder Bruno Guimaraes carries a special 'Barcelona clause'.
Guimaraes penned a new deal to 2028 a week ago, which included a 100m buyout clause.
Sport reports the price is lower for Barcelona. Guimares wants to keep the door open for a move to the Spanish giants.
The price for Barcelona would be around 65-70m. Sport reports the clause for all other clubs is "85m".
This season, Guimares has scored one goal and one assist in eight games in the Premier League. Newcastle are in eighth place in the table.
