The only reason Victor Oshime hasn't signed for Chelsea already is due to the absence from European Competition. Chelsea, is the perfect club for Victor Oshime. He doesn't need to struggle so hard to fit in, African player's are well used, as we have names of greats who have represented the club gallantly.

Despite the fact that no player is bigger than the club, Victor Oshime, needs another level of football and that's not in that team, same goes to Khivicha Kvaratskhelia, such a player deserves to wear the Los Blancos Jersey.
The move wouldn'take sense this season, but immediately Chelsea does qualifies, Victor Oshime would be the number one player leading Chelsea's attack.
