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.
Ajax midfielder Christian Eriksen says he has not heard anything about a potential transfer amid reported interest from Liverpool.
The Reds have been heavily linked with a summer swoop for the Denmark international, who is about to enter the final year of his contract at the Amsterdam ArenA.
Those rumours have increased after Brendan Rodgers' men missed out on the signature of Shakhtar Donetsk star Henrikh Mkhitaryan, who joined Borussia Dortmund earlier this month.
Ajax boss Frank de Boer revealed over the weekend that he would not stand in Eriksen's way, should the 21-year-old express a desire to move to Anfield this summer.
When quizzed on his future, Eriksen confirmed he is ready to move on to a bigger club, but stressed he had yet to hear of any offer.
"I do not know more about this than you," he told Voetbal International. "If I leave, I have to go to a club that is bigger than Ajax in every way.
"But no clubs like that have shown interest yet. I've read a lot about it, but heard nothing from the club."
