Manchester United remain frontrunners to sign Roma and France midfielder Manu Kone, 25, but face strong competition from Premier League rivals Arsenal.
Liverpool have renewed their interest in Athletic Club winger Nico Williams, with the 23-year-old Spain World Cup winner understood to have a £77 million release clause.

AC Milan have made Genk wonderkid Konstantinos Karetsas, 18, a priority target for next summer, although the Italian giants may need to sell Rafael Leao, 27, to finance a move for the highly rated winger.
