#3 Armando Izzo
It is no secret that Serie A is the home of Europe's best defenders. Joining Torino for a mere €8 million in 2018, Armando Izzo has quickly established himself as one of the best defenders in the Italian top division. He endured tough seasons at Genoa due to a string of injuries, making just 16 appearances in the 2017/18 campaign.
However, Walter Mazzari remain faithful of the defender's enormous potential. Izzo became an instant hit for Torino, amassing no less than 37 appearances as a starter in his debut season. Torino just conceded 37 goals last term, with only top clubs such as Juventus, Napoli and the Milan duo having a better record.
A no-nonsense defender with an all-around defensive capability, Izzo would be a valuable asset for United. He recorded impressive 2.1 tackles, 2.4 intercepts and 3.8 clearances per game. The Italian also excels in aerial battles, winning 3.2 aerial duels on average last term. He would be available for around €30 million.
