Igor Akinfeev is one of the most promising goalkeepers in the World. He is now 20 years-old and is CSKA Moscow's main keeper since 2003. Remember CSKA reached the UEFA Cup final in the last season... I don't think there's anyone as good as him if comparing goalkeepers his age. Maybe Roma's Gianluca Curci could be comparable... But Igor's potential his higher. Nigmatullin and Ovchinnikov are exponents of an older generation, and they simply can't stop Akinfeev's potential. He's commanded the Russian net since age 19. I don't think there are any particularities Akinfeev needs to work on. He'll for sure be on the same level of Buffon or Cech in the near future. I cannot assure it, but I strongly believe Akinfeev will someday be the best goalkeeper of the World.
