This could be it for several Mexico national team players.

Juan Carlos Osorio has called in 26 players to be part of his squad to face Iceland and Croatia in March friendly matches, but the Mexico manager says he already knows who will be on his list to go to the World Cup. We've seen over the past few years, though, that Osorio is now willing to have his mind changed. The players not currently on the list still could change his mind, while some of the players who may be set for the trip to Russia could need to shore up their spot.

Starting from most necessary to least, we've taken a look at the players who have to impress the Colombian coach and his staff this month to have any chance of fulfilling the dream of representing their country at the sport's biggest stage.

The San Luis Potosi native clearly is on the radar, but he's played just 16 minutes with El Tri. He needs to add to that total this month to have a chance at the final squad.AdvertisementAdam HungerJorge Hernandez"Burrito" played the second half of El Tri's game against Bosnia and Herzegovina in January, following up on a decent showing in the Gold Cup. After not being called in for a World Cup qualifier in his career, though, it's tough to imagine the 28-year-old will be at the World Cup finals without doing something extraordinary in the final tune-ups.Getty ImagesJonathan GonzalezThe 18-year-old midfielder has only suited up for Mexico once, but Osorio and his staff like what they've seen from Gonzalez. He still needs to work for his place on the roster, which the Mexican federation has taken great pains to note was not guaranteed in exchange for the California-born midfielder's decision to file a one-time switch after representing the U.S. at the youth level. Gonzalez is a talented player, but does he do enough to merit a spot in Russia? He'll have to prove it.USA Today SportsEdson AlvarezThe 20-year-old defender only recently was back in the Club America starting lineup thanks to a mix of injury and suspension. His struggle for club minutes is a concern, but his versatility may outweigh those issues. Across an already thin back line, Alvarez's ability to come in as a right back, a center back or even play in the midfield is attractive to Osorio. Solid cameos in March may lock up a spot, though a poor performance could raise doubts.
