Leicester boss Ruud Van Nistelrooy has denied he was shocked by the Foxes' inability to spend in the transfer window and says they have to cope with the "restrictions".
Defender Woyo Coulibaly was the only signing, arriving from Parma for £3m, while the Foxes rejected Sunderland's offer for midfielder Kasey McAteer on deadline day.
Leicester go to Manchester United in the FA Cup fourth round on Friday with Van Nistelrooy naming teenagers Jeremy Monga, 15, and Jake Evans, 16, on the bench.
Facundo Buonanotte and Odsonne Edouard are on loan from Brighton and Crystal Palace respectively, meaning the Foxes could also not make any domestic loan signings - without sending them back - in the window.
