New Waratahs coach Michael Cheika says that he has not been in contact with Ireland captain Brian O'Driscoll over a potential move to Sydney to play Super Rugby.
Cheika was O'Driscoll's coach when he was in charge of Leinster and the Ireland captain has sparked speculation that he could end his career playing Super Rugby.
O'Driscoll told British media this week he would consider playing in the southern hemisphere competition when his current contract ends in June.
"Obviously I know Brian very well. It is no secret that he is one of a number of top players over there who would love to come down and play in the Super 15," Cheika told AAP.
"I saw him before I left - I went to say goodbye. But we haven't spoken since. I wouldn't want to do that to him or the club. He is in the middle of a season, the Heineken Cup is still on and they are focusing on that.
"It is still my club and it is very close to me and I would not want to disrupt their season. That is Brian saying how he feels about things and what he might like to do.
"It would be a big decision for him to leave Ireland but the thought is there with all the top players they would all love to come down and have a try - there is no doubt about that.
"We don't have a marquee player... and whether we would go down that road is something we would have to discuss."
