When choosing a good goalkeeper, you shouldn’t focus only down on his rating. There are two fundamental attributes for choosing a good goalkeeper: reflexes and diving. The first measures a goalkeeper’s agility when making a save. The other measures the goalkeeper’s capacity to make a save when jumping.
