AC Milan vice-president Adriano Galliani admits they're facing frustration in their bid for CSKA Moscow striker Keisuke Honda.
CSKA are refusing to sell the Japan international.
"CSKA Moscow don't want to sell Honda, and if they keep on saying no then there's nothing we can do," said Galliani.
"The deal is on hold, also because the CSKA Moscow President is on holiday right now."
