Ole Gunnar Solskjaer is facing frustration with Manchester United's board over his pursuit of Bruno Fernandes.
United are not so convinced by the Sporting Lisbon star, 24, while Solskjaer believes they should be willing to pay the 70m required for the midfielder.
Correio da Manha says United don't want to pay more than 50m for a player who doesn't regularly play in the Champions League.
This is despite the fact that Fernandes contributed to 50 goals in all competitions last season.
He has even been called the 'next Frank Lampard' due to his goalscoring ability, which saw him hit the back of the net 31 times last season.
