#2 Mauro Icardi
Mauro Icardi has endured a frustrating spell for Inter Milan and spent the bulk of 2018/19 season on sidelines due to controversies. The striker lost his club captaincy role, and his Inter future lies in jeopardy.
Despite his problems and intermittent playing time, Mauro has managed 11 goals in Serie A. The Argentine is one of the best strikers around and is Inter's consistent performer.
Real Madrid enquired about the availability of Mauro Icardi and Juventus arrived late in this picture. Inter Milan is keen on signing Romelu Lukaku and could favour a player plus cash transaction for him. Mauro Icardi could be a part of the exchange deal.
A player swap is a favourable situation for both the parties as United have lacked a reliable outlet of goals, and Inter Milan will get their desired target in the form of Lukaku.
#1 Antoine Griezmann
Antoine Griezmann is perhaps the most coveted name on this list. A few days back, the French centre-forward announced his decision to leave Atletico Madrid. Barcelona are Griezmann long-term admirers and probably his next destination.
The recent reports have suggested that Camp Nou bosses are reluctant to pay Atletico Madrid forward's £108m release clause, and it has opened a way for Manchester United to get hold of the Frenchman.
Griezmann isn't a traditional striker but plays as an inside forward. The Frenchman's proven goalscoring record indicates that he could thrive in a false-nine role at United. He provides mobility and work-rate in the attack, which Solskjaer demands from his side.
