A Welsh news website has listed Tana Umaga as a possible contender for the Scarlets coaching job.

Welsh media are speculating that Blues coach Tana Umaga and Crusaders assistant Ronan O'Gara could be potential contenders to coach Scarlets once New Zealander Wayne Pivac moves onto the Wales job.

Pivac will coach Scarlets for the 2018-19 season before replacing Warren Gatland at the Welsh coaching helm next July.

Scarlets general manager Jon Daniels told Wales Online the 2016-17 Pro12 champions would "trawl far and wide" for a new coach.

"If it is on our doorstep, then fine. If it is New Zealand, South Africa, Australia, then that is what we will do."

Pivac's assistant, former Wales fly half Stephen Jones, is widely seen as the logical replacement at Scarlets but he could possibly join Pivac in the Wales set-up.

Wales Online listed three coaches with New Zealand connections as possible alternatives, including ex-All Blacks captain Umaga, who is contracted to the Blues until the end of the 2019 Super Rugby season.

It said Umaga had been "head coach of an underperforming Blues franchise since 2016" and had "brief experience coaching in Europe with Toulon".

Of O'Gara, it said: Who would have thought the former Ireland fly-half would end up with the Crusaders in New Zealand? The Crusaders and the Scarlets also sing from the same hymn sheet."

Another alternative was former All Blacks No 8 Filo Tiatia, who was "an icon across the bridge at the Ospreys", had been coaching in Japan and is now [assistant-coach] at Auckland, where Pivac has the odd contact".

Other names on the Wales Online list were ex-England coach Stuart Lancaster - now an assistant-coach at Pro14 and European Cup champions Leinster - former Scarlets coaches Phil Davies and Simon Easterby and ex-Wales halfback Dwayne Peel.
