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.
QPR manager Harry Redknapp has revealed record signing Christopher Samba is already attracting interest from an unnamed "big club".
The Premier League's bottom side pulled off something of a surprise on transfer deadline day, breaking the transfer record they set earlier in January to bring in the former Blackburn defender from Anzhi Makhachkala.
Samba has penned a four-and-a-half-year deal with the west Londoners, who remain in serious danger of dropping in the second tier.
QPR are six points adrift of safety heading to Swansea on Saturday but Redknapp remains confident of staying up - and keeping Samba.
"When people say he is a risk and you're putting the club in a difficult position if it went down, you could sell Chris Samba for what you paid or more at the end of the season if you wanted to," Redknapp said. "Without a shadow of a doubt.
"I had a chairman ring me a week ago asking me about him and saying 'what would you do if you went down?'
"I said 'we ain't going to go down' but he said 'well, we want to sign him...if we'd have known he was available'. I am talking about a big club.
"There will be big clubs wanting him. Big clubs, not a danger.
"I could see a club not too far away 18 months ago and I thought 'surely they've got to take Samba?' I was always after Samba at Tottenham. Always."
