According to Ole (h/t AS), the Red Devils boss is willing to spend heavily to sign the 25-year-old and is hoping the club will back him financially.
Icardi is believed to have a release clause of €110 million, but Mourinho also needs to convince him to swap the San Siro for Old Trafford, per AS.
Icardi joined Inter Milan from Sampdoria in 2013 and has become a consistent goalscorer for the Nerazzurri. Squawka Football highlighted how impressive he was last season:
His performance do not appear to have gone unnoticed. He was linked with a move away from the San Siro during the summer transfer window.
The Argentinian emerged as a potential replacement for Cristiano Ronaldo at Real Madrid, according to Marca's Jose Felix Diaz and David G. Medina.
The forward's wife and agent, Wanda Icardi, told Tiki Taka (h/t Football Italia) that Juventus and Napoli were both interested in the 25-year-old over the summer.
However, Icardi could be set to commit his future to Inter Milan. He is close to signing a contract extension that will keep him at the club until 2023, according to La Gazzetta dello Sport (h/t Calciomercato.com).
Manchester United are hardly lacking for attacking options with the likes of Romelu Lukaku, Alexis Sanchez, Marcus Rashford and Anthony Martial all in the squad.
Lukaku is the club's first-choice striker and has proved to be a good buy from Everton. Opta noted his goalscoring record:
20 - Romelu Lukaku has scored 20 goals in 39 Premier League apps for Man Utd; only three players have reached 20 PL goals for the Red Devils in fewer games than the Belgian - Ruud van Nistelrooy (26 games), Robin van Persie (32) and Dwight Yorke (34). Potent. #WATMUN https://t.co/uu3PIbmeeT
It's difficult to see where Icardi would fit in at Old Trafford and whether the club would be willing to sanction such an expensive transfer.
Manchester United executive vice-chairman Ed Woodward refused to sanction moves for several players Mourinho wanted to bring in over the summer, per the Guardian's Daniel Taylor.
