#2 Lorenzo Insigne
Lorenzo Insigne is a 27-year-old left winger for Napoli and has also featured for Italy's national team 30 times since making his debut back in September 2012.
Quick and agile, Insigne constantly puts defenders on the backfoot. Alongside the left winger role he primarily takes up, Insigne can also be deployed as a second striker, a position in which he is deadly. His pin-point shooting accuracy is enough to scare the opposition into tightening up as much as possible at the back, lest he gets a hold of the ball.
He would be superb out on the left flank in place of Alex Iwobi, who has struggled this season. Before, Arsenal had Alexis Sanchez out on the wing, but after his departure to Manchester United, the Gunners didn't take the time to replace him and have paid the price.
However, how realistic a transfer for Insigne to Arsenal would be is questionable, given his price tag of £70m - which would likely rise to about £80m, judging from just how well he has played this season. Napoli would be very hesitant to lose him, hence the price spike.
