Newcastle United defender Chancel Mbemba is in limbo as he waits to complete a move to Porto.
A Bola says Newcastle have demanded £8million for the defender but an offer of £6million is on the table from Porto since last week.
United could not agree on a fee for the defender towards the end of last week but Mbemba is keen for answers about his future after agreeing to personal terms with the Champions League-bound team.
Porto will look to get the situation resolved this week but Newcastle are standing firm on price tags this summer after being quoted some sky-high valuations on potential incoming players.
