Sky Sports understands Newcastle have missed out on audacious late bids for Bryan Ruiz and Liam Ridgewell.
The Magpies attempted to hijack Fulham's move for highly-rated Ruiz, with the Cottagers having agreed a fee with FC Twente for the Costa Rica international striker.
The St James' Park outfit made an enquiry to Twente about a possible move and had a helicopter on standby to aid negotiations.
Despite indications from his agent that he would talk to the Magpies, he did not arrive at the arranged meeting point.
Instead, Sky Sports sources understand Ruiz has joined Fulham.
