Carter, who has just been named the International Rugby Board's Player of the Year, would be a stellar signing for any European outfit and would be a major addition to the continent's premier club competition.
The 30-year-old has already enjoyed one stint in the Heineken Cup but that experience of the tournament was shortlived after injury wrecked his spell at Perpignan in 2008/09.
An Achilles problem stopped him from playing in the Round 5 and 6 Heineken Cup matches against the Ospreys and Benetton Treviso, meaning he featured just once in the competition.
That solitary appearance came against Leicester Tigers at the Stade Aime Giral in December 2008, a match in which Carter certainly left an impression.
The Kiwi playmaker kicked four penalties and converted two Gerrie Britz tries for a 16-point haul in a 26-20 win over the Tigers.
Carter then ruptured his Achilles tendon in a Top 14 clash against Stade Francais later in January '09 as he saw his first French adventure cut short just days after Perpignan had been knocked out at the Heineken Cup group stages.
