The Vodafone Fiji 7's team can still expect a stiff challenge from Samoa in the pool match of the England 7's although Samoa has not been in its best form.

Samoa was relegated to the Shield competition in last weekend’s Scotland 7s after the side lost its two pool matches.

Samoa is expected to turn around its performance and would also try to cause problems in Fiji’s quest to win its first Series title since 2006.

Samoa will have players like Lolo Lui, Alatasi Tupou, Falemiga Selesele and Belgium Tuatagaloa.

Pacific rivalry is expected to be at its very best when the two sides clash at 12.12am this Sunday.

Speaking from London, Fiji 7's coach, Ben Ryan said they will have to beat all those teams who will try to knock them over.

Fiji will play Argentina at 9.06pm Saturday and Canada at 3.18am Sunday in its two other pool matches.

The cup quarters start at 9.28pm Sunday, the cup semis are at 1.18am Monday while the cup final is at 4.27am Monday.
