Samoa international flanker Taiasina Tui'fua says his switch to Newcastle Falcons in the Premiership is a significant move.
Tui'fua, 27, , but delayed joining up with the squad because of involvement in the World Cup.
"I've been watching some Premiership rugby and it's a good competition," Tui'fua told BBC Newcastle.
"It's a challenge to come here and play. It's a big move for me."
The Premiership has proved a popular destination for Samoan players.
At the recent World Cup, Tui'fua was one of 11 Premiership representatives in the national team squad with Eliota Fuimaono-Sapolu at Gloucester, Johnny Leota of Sale and Leicester's Alesana Tuilagi among them.
"It's nice to be here as some of the older players back home have played here in the Premiership. I've lots of friends here," Tui'fua said.
"There's a lot of Samoan international players, and players from New Zealand here.
"I've got [former Counties-Mankau team-mate Andrew] Van der Heijden here and Jamie [Helleur], who were good friends from schools so it's great."
