Isa Nacewa "can't wait" to get back into action with Leinster after coming out of retirement to re-join his old side.
Nacewa was coaching with the Blues earlier this year in Super Rugby after retiring in 2013 and then returning to New Zealand.
The 33-year-old then surprised many with his decision to put his boots back on and head back to Ireland.
Nacewa believes his experience of coaching will be a big asset as he settles back into life with the three-time European champions.
"Personally for myself I just can't wait to get back and play," Nacewa told the PRO12 website.
"Being on the other side of the fence in New Zealand (with the Blues) I've learned a lot in the last two years.
"Fingers crossed I can give as much knowledge as needed to the young guys. I've still got to perform to the best for myself week in, week out too, but the more the young guys can feed off my experience, then the better for us.
"I think the biggest thing that's changed is the faces. There's still massive motivation and drive at the club."
