Alvarez Fifa coins is located at the Sportiz sports Fut 14 Coins facility, located on the western side of the southern island. Again, either a frontal approach or a water approach works here, with the water approach probably being the best bet. If you wish, you can head around on the rocks that ring the northern side of the facility and use them as a perch from which to shoot at the enemies below.Setting the bosses on fire will often prevent them from attacking for a moment.
Alvarez himself will likely be in a ring of stone on the beach behind the facility. You'll want to clear out his guards first before dealing with the man, but be careful, as he'll continually chuck grenades at you as you run around, and he can throw them far and accurately. Luckily, if you deal with the bodyguards, Alvarez should prove to be a fairly easy kill. Charge him, melee him, grenade him, shoot him; whatever. He'll try to throw grenades at you, but they're easy to run from while you're on the ground.
