The 22-year-old is becoming an increasingly important member of the Argentina national team, and his partnership with Lionel Messi is a contributing factor in his preference for a move to the Camp Nou. Martinez joined Inter from Racing Club for £20 million in 2018 and has a €111-million release clause written into his contract.
The Buenos Aires native has flourished alongside ex-United marksman Romelu Lukaku in Inter's attack this term, scoring 16 goals across 24 starts in Serie A and the Champions League.
A Martinez snub would be yet another setback in United's search for a striker. They failed to land Erling Haaland during the January transfer window - the Norwegian has since scored seven goals in under 150 Bundesliga minutes for Borussia Dortmund - and Ogden claims they are preparing to give Alexis Sanchez a second chance when he returns from his Inter loan after this season.
