Tottenham are desperate to bolster their midfield despite the signing of Tanguy Ndombele.
The Frenchman joined for a club-record £62.5m to mark their second signing of the summer after Jack Clarke of Leeds.
It signalled the end of a self-serving hiatus from the transfer market where they did not sign a player for two windows.
But Daniel Levy wants to bankroll Mauricio Pochettino this summer after seeing his side reach the Champions League final only to fall at the last hurdle.
Liverpool beat them 2-0 and conquered Spurs and the Argentine manager wants to strengthen his midfield.
Ndombele undoubtedly improves that position but Pochettino wants goals and there are not many in the game than Fernandes of Sporting.
The Portuguese ace scored 32 goals in all competitions as well as laying on a further 18 assists for his team-mates.
He also helped his country to the Nations League trophy but United are chasing the 24-year-old as well.
However, according to A Bola, Spurs have been boosted by the news that the Red Devils’ reluctance to meet the club’s £70m price-tag.
The Lions are demanding a massive fee after his stunning year in the Primeira Liga though the player is expecting a move away.
But Tottenham may also think twice about signing Fernandes for that kind of money.
After already splashing out a club-record fee on Ndombele, Levy may turn his nose up at having to break that again.
It comes not long after news that the north London outfit refused to meet Real Betis’ asking price of £60m for Giovani Lo Celso.
The Argentine midfielder has long been on the club’s radar but are trying to bring the price down.
