Virgil van Dijk claims he knows nothing of interest from English clubs and is keen to prove himself in the Champions League with Celtic.
QPR loanee Tom Carroll wants to "make it at Tottenham" but is prepared to consider all of his options at the end of the season.
The Costa Rica forward is now just waiting for Fulham and Dutch side PSV to finalise their agreement before a deal can be completed.
"He did have a medical at the club on Monday and I can say that everything went well," Ruiz's agent Rene Vijt said.
"Now it is up to the two clubs before anything else can happen."
Ex-Fulham boss Martin Jol made Ruiz his biggest signing in 2011, recruiting the 28-year-old for a reported £10.6million fee.
The 61-cap international has struggled to impose himself at Craven Cottage though, and is now set for a swift exit.
New Fulham head coach Rene Meulensteen admitted last week that he would allow Ruiz to leave this month.
"I wouldn't call his signing a mistake because at that time it was probably for Fulham the right choice and the right investment," Meulensteen said.
"Don't get me wrong, he is a very good player. I've come in, I've looked at the squad, worked with these players, I've picked my teams on what I think are the right reasons and motivations, but I can also understand Bryan's point of view."
