Swiss side Basel have refused to comment on reports that they have offered a deal to Sol Campbell.
The former England international is out of contract at Fratton Park this summer.
As yet the 34-year-old is yet to decide on his future, but he has long been linked with a move abroad to end his career.
Switches to America's MLS and Spain's La Liga have previously been mooted - but now a switch to FC Basel is being suggested.
Reports have claimed that Basel are ready to offer Campbell a three-year deal to move to Switzerland.
However, when quizzed about the Campbell rumours Basel vice-chairman Bernhard Heusler refused to comment.
"We are not going to make any statement on the truth of this," Heusler told Basellandschaftliche Zeitung.
