While the Albiceleste captain is an automatic choice for his nation, there is fierce competition to accompany him in Russia

JUAN MABROMATA/AFP/Getty Images1Dario BenedettoIf it were not for a cruciate ligament tear suffered back in November, Benedetto would have had a real chance of making Argentina's World Cup list. The Boca striker had netted 12 goals in as many games prior to his injury, and also featured in the Albiceleste's last four qualifiers, albeit without hitting the net. Even if he does beat the odds and make it back to competitive action before June, however, his World Cup dream is effectively over.AdvertisementGetty2Cristian PavonThe Boca Juniors star joins Martinez in the squad as one of Sampaoli's picks from the Argentine Superliga. Pavon made a huge impression in his international debut back in November, laying on two goals for Sergio Aguero in clashes against Russia and Nigeria, and his prowess down the right marks him out as a useful option in Argentina's star-studded attack.Getty3Lautaro MartinezAt just 20, the Racing Club wonderkid's name is on everybody's lips. Sampaoli has already visited the Cilindro on no less than three occasions to watch Martinez, who obliged the Argentina coach with an incredible seven goals to earn his first call up to the senior Argentina side. The World Cup may be arriving just too soon for the striker, but his talent is undeniable and a strong showing in this double-header might just tip the balance and see him make Russia as a wildcard pick.Getty4Angel CorreaWhen injury forced Aguero out of March's clashes, Sampaoli turned to an unexpected face in order to fill the gap in his squad. Atletico Madrid's Correa got the nod ahead of both Icardi and Dybala to join the squad, a chance he has richly earned thanks to his excellent performances at the Wanda Metropolitana. The 23 year old offers depth both through the middle and out wide in the Argentina attack and will be eager to add to his collection of seven caps against Italy and Spain.
