Manchester United have stepped up their interest to sign Inter Milan forward Lautaro Martinez this summer.
The Argentine has been in excellent form this season, scoring 21 goals in 45 appearances. He also scored in the Champions League last-16 second-leg against Liverpool in March.
That has sparked interest from the Red Devils, who are searching for a new striker with Edinson Cavani out of contract and Marcus Rashford's future in doubt. Cristiano Ronaldo, who recently turned 37, has netted 23 times in 36 games this term.
