The 24-year-old Spaniard spent three unproductive years at Anfield and after initially struggling to impress at the San Siro, blossomed during a loan spell at Genoa during the 2015-16 season.
Since then, he’s made 58 appearances for the Rossoneri, scoring 13 goals. A sign of his progress came with his first international call-up for the World Cup Qualifier against Italy. His debut for Spain came in November’s friendly against Russia.
Spurs midfield behind Dele Alli and Christian Eriksen is struggling for fitness and form. Mauricio Pochettino is conscious that he will lose one or both in the summer and wants to strengthen his squad in January to integrate new players before that.
Milan have their own problems to deal with. They are likely to find their request for exemption from FFP regulations runs onto UEFA rocks and will need to sell before they can strengthen their own squad, as well as cutting their wage bill.
Suso, while being a driving force of the team, is a highly saleable asset and Tottenham believe they can persuade the fallen European giants to sell in the next transfer window.
