Sky Sports understands West Ham's pursuit of Ishak Belfodil has hit a stumbling block.
West Ham had agreed an initial loan deal with Inter, but Belfodil is co-owned by Parma - which is where the problems have emerged.
Parma want the move to be permanent because they want their share of any potential transfer fee now.
So as things stand Parma, who own 50 per cent of the player, are holding up this deal.
West Ham are also trying to sign Lacina Traore, who joined Monaco from Anzhi Makhachkala earlier this month, and they will have a work-permit hearing for him next week.
