Rivals chasing highly-rated Spanish winger this January.
Arsenal and Liverpool are being strongly linked with a bid to sign Lazio youngster Keita Balde Diao in January, according to the Daily Express.
The 19-year-old winger is one of the most highly rated young talents in Serie A at the moment after some eye-catching displays for the club since his move from Barcelona.
Both the Gunners and the Reds could do with new signings in the attacking midfield department this season, with both sides looking somewhat short of quality up top at the moment.
Liverpool have suffered since selling Luis Suarez to Barcelona during the summer, with some of their new signings Adam Lallana and Lazar Markovic failing to make an impression at Anfield so far.
Arsenal, meanwhile, have been without injured stars such as Olivier Giroud and Theo Walcott in attack, while the likes of Mesut Ozil and Alex Oxlade-Chamberlain have not made the desired impact in the team so far this season.
Arsene Wenger and Brendan Rodgers are both said to be big fans of Keita, with the clubs paying close attention to his progress for some time now.
The two teams now seem on alert as Lazio will accept offers in the region of £24m for his services this January.
