Arsenal manager Unai Emery has undoubtedly brought some spark to the Gunners since he took over from Arsene Wenger last year, however, he needs to fine-tune some part of the team if he must lead the North London club to their first Premier League title in more than a decade.

Arsenal's attacking department needs some reinforcements before the start of next season and Emery should be ready to get new attack-minded players, especially wingers.

Alex Iwobi, despite his  rejuvenation under the Spaniard, hasn't been consistent all through this campaign, while Henrikh Mkhitaryan is not as prolific as many Arsenal fans would love to see.

To this effect, Emery will have to join the race for  Villarreal youngster Samuel Chukwueze in the summer transfer market.

The 19-year-old is currently rated as one of the best teenagers in La Liga, but has seen game time too hard to get since Calleja's return to the helm of affairs in January.

Chukwueze's dribbling skills will surely add more quality to Arsenal's performance at either flanks of the pitch.

His pace is another reason why the North London club must make a swift move for his signature.

His speed will no doubt boost the team's counter-attacking ability while his impressive shooting accuracy will help the team convert most of their goalscoring opportunities.

The Nigerian star player often operates as right winger for the Spanish side despite being a left-footed player and that speaks more of his versatility.
