Semi Radradra has asked Parramatta to keep space under their salary cap in 2018 to allow him to return to the Eels for the second half of next season after a stint in French rugby.

The Fijian winger produced an incredible individual display in the 52-34 defeat of Brisbane at Suncorp Stadium on Thursday night, weaving his way around defenders with ease in a four-try performance as Parramatta surged into the top four.

Radradra will join French rugby team Toulon after this season but said in the aftermath of the try-scoring spree in Brisbane that his intention was to "try something different and then come back to the NRL".

Should be decide to do that after one season in Europe, Radradra could potentially be in a position to re-join Brad Arthur's team next May and it has emerged that the 25-year-old has asked the club keep that option available by leaving space in next year's salary cap for his return.
