Cardiff Blues star Gavin Henson has admitted his return to The Liberty Stadium to face Ospreys on New Year's Day is potentially "awkward".
"That's going to be an awkward one," said Henson.
"But I'm looking forward to it."
The 2005 British and Irish Lion and double Wales Grand Slam winner suffered a dislocated wrist as he tried to make Wales' 2011 Rugby World Cup squad and that injury kept Henson out of action until Welsh rugby's festive derbies.
The 29-year-old admits the Blues' visit to Swansea has been on his mind since in October and admits he "may have a point to prove" on Sunday.
Henson started his career at Swansea but joined the Ospreys when regional rugby was formed in 2003.
The Bridgend-born player scored 773 points in 85 games for the region but he injured his ankle in an EDF Energy Cup semi-final defeat to Gloucester in March 2009, which proved to be Henson's last Ospreys game.
"Obviously when I saw the fixture list and I signed for the Blues it kind of looked like that could be my comeback game against the Ospreys," said Henson. "Which would be slightly ironic.
"It will be a little bit strange - [I have] a lot of friends [at the Ospreys].
"I love the players down there, but obviously [there's] a lot of history going on there as well, so [it's] a big game for me."
Henson's former coach Scott Johnson, the Ospreys director of rugby, took a hard line over the player's departure from the Ospreys.
But Johnson is looking forward to Henson's first return to The Liberty Stadium after his seven-year stay ended in October 2011.
"It will be good to see Gavin back as he is a wonderful rugby player at his best," Johnson said.
"He is a talented kid and will be a formidable opponent."
