With Danny Welbeck on the way out and Henrikh Mkhitaryan yet again faltering in north London, wingers are an absolute must this summer for Unai Emery.

The Spaniard has always preferred a system with wide players in the attack, which is why it must have been a surprise for the former PSG man when he arrived at Arsenal that his options out wide were more than lacklustre, with Alex Iwobi and the Armenian international the only natural choices.

A lack of wide men has seen the Gunners resort to more unorthodox formations this season, such as a 3-5-2 or a 4-1-2-1-2, but the end goal for Emery is to implement his favoured 4-2-3-1. However, to do that, you need quality wingers, which is where Arsenal are slacking massively.

And now according to Goal, Nicolas Pepe has caught the eye of Arsenal. The Lille attacker has been one of the breakout stars in Europe this season, scoring 22 goals and assisting 11 as the Ivorian led the Ligue 1 side to second place in the table.

Competition for the winger's signature is already heating up, with Arsenal having to face off against the likes of Bayern Munich and Inter Milan. But, if the Gunners can define the odds and sign Pepe, it would be a turning point for the club.

Valued at £36 million on Transfermarkt, Pepe would be as important a signing for the club as Lucas Torreira was last year.

The winger offers Arsenal much-needed width and pace that the club have lacked on the wings this season, and his goalscoring exploits this campaign will lessen the attacking responsibilities put upon Alexandre Lacazette and Pierre-Emerick Aubameyang, who the Gunners have relied on heavily.

Pepe will be an expensive signing for Arsenal, but if the club are able to beat out the competition and offer Lille the money, Emery will be signing a player who has the ability to take the club back to its past glory days.

Arsenal fans, would Pepe be a good signing this summer? Let us know!
