A move for Barcelona midfielder Sergi Roberto could be on the cards.
According to Don Balon, Manchester United are willing to pay his £36.4m (€40m) release clause.
Roberto is wary his playing time at the Nou Camp could be limited this term.
Barcelona are on the brink of signing Paulinho and want Philippe Coutinho from Liverpool.
He is open to staying at the club but could consider his options later this month.
Juventus are also interested in snapping him up.
Tottenham are set to launch another bid for Anthony Martial.
Reports in France over the weekend suggested Spurs had an offer knocked back by United.
According to TransferMarketWeb, they are ready to try again for his signature.
United also had to reject a loan bid from Inter Milan for Martial.
The 21-year-old netted in yesterday's 4-0 win against West Ham.
Meanwhile, United are battling Chelsea for Fiorentina winger Federico Chiesa.
Italian journalist Niccolo Ceccarini claims the two clubs "have moved heavily" for the 19-year-old's signature.
Chiesa scored five goals and provided four assists in 34 appearances for Fiorentina last term.
He has four years left on his contract.
