Kim Kardashian -- I'm a Soccer Mom Now!

Hope Solo may have some competition ... in about 18 years ... 'cause Kim Kardashian's daughter is a SOCCER PLAYER now ... and she's already got her sights set on the goalie job.

Kim K posted a pic of 2-year-old North West out on the soccer pitch -- complete with cleats and shin guards ... along with the caption, "Officially a soccer mom! #MyLittleGoalie."
