The Gunners need to strengthen their attack this summer having struggled at times last season, and manager Arsene Wenger certainly needs to add some pace to his front line. Arsenal failed to get in behind defences after the injury to Theo Walcott in January, and they have already reportedly been locked in discussions to land Barcelona star Sanchez.
The former Udinese man is set to be sold by Barcelona as the Catalan giants look to rebuild this summer, and whilst Liverpool want to bring Sanchez to Anfield, speculation continues to suggest that Alexis would instead prefer to sign for Arsenal – despite Brendan Rodgers' men finishing above Arsenal last season.
Yet whilst a deal to land the 25-year-old could be drawing closer, the Gunners aren't content with just one Chilean strike star – with speculation now linking Arsenal with a move to sign Sanchez's international strike partner Vargas from Napoli having impressed with Jorge Sampaoli's side in Brazil at the World Cup.
The young forward became one of the hottest players in South America during his time with Universidad de Chile, scoring 32 goals in 78 games before earning a move to Europe with Napoli. His spell with the Serie A side has been underwhelming at best, scoring just three times in 28 appearances. His loan spells away from the club have been more fruitful, scoring 14 goals in 62 games with Gremio and Valencia – leading to more speculation over his future with Rafael Benitez's side.
Whilst his record in Italy won't exactly fill Arsenal fans with confidence over the prospect of him arriving in North London, Vargas impressed at the World Cup with a goal and two assists, and he possesses exceptional pace to trouble defences in behind - which Arsenal desperately need to add to their attack.
His versatility to play out wide or through the middle of the front line would make him a valuable addition, and whilst he isn't a big name attacking capture that Arsenal fans want and expect, he could well surprise fans off the back of his World Cup performances.
