Nigeria defender Taye Taiwo's proposed switch from French champions Marseille to Spanish side Atletico Madrid has stalled, BBC Sport understands.
Taiwo had been expected to finalise the deal on Wednesday but the player's agent Michael Coker says the deal has hit problems.
The Nigerian had agreed personal terms with the Spanish side on Tuesday but Marseille are apparently insisting they want the transfer fee upfront rather than in instalments in the future.
