He appeared in two games at the 2014 World Junior Championship and was 0-1 with a 2.65 goals against and .897 save percentage.
Nalimov is an interesting goalie with some good upside, but is a bit streaky and needs to work to boost his game-to-game consistency. He needs to gain some pro league experience, but he showed some good skills in the Russian junior league, in particular related to his reflexes, use of his size, and agility. Nalimov also needs to improve his goaltending technique and positional play. He also tends to leave some unneeded rebounds, and tends to give up a bit after a soft goal or some fast goals.
