#1 Mauro Icardi
Unarguably the most important player for Inter Milan in recent years, the Argentine is a bonafide world class striker who bangs goals in for fun, and Inter Milan have benefitted immensely from his potency in front of goal.
The 24-year-old finished as joint top scorer in the Serie A last season with 28 goals alongside Ciro Immobile, and his goals were crucial in helping the Nerrazurri qualify for the Champions League after an eight-year hiatus.
Icardi has shown that he belongs on this stage so far, with two goals from two appearances, the first of which was a worldie from outside the box against Tottenham, before a calm finish past PSV put Inter ahead in the second match.
Barcelona would be wary of the danger posed by the Inter captain, as he is one of many players who could hurt the Spanish champions.
