The former Parramatta and Indigenous All Star took his season's touchdown tally to 27 as Matty Peet's side returned to winning ways after their shock defeat at Wakefield.

French's treble was his third of the campaign in addition to his record-breaking seven-try haul against Hull FC.

Out of contract at the end of the season, French's new scoring feat will again revive speculation about his future at the DW Stadium.

He is the leading tryscorer in the league and is currently three clear of next best Ken Sio of Salford.

Wigan, who host arch-rivals St Helens next time out, were fast out of the traps. French kicked ahead and re-gathered to open the scoring after just four minutes.

Jai Field and French have wreaked havoc on Super League defences this season and when the former's surge from deep spreadeagled the visitors' cover, French was in support to run over unopposed after 43 minutes.

The hat-trick five minutes later stemmed from Tony Gigot's loose pass and a 70-metre sprint by French.

The massive victory all but ends Toulouse's one-season stint in the competition.

Bottom-of-the-table Toulouse have recorded just five victories all season and trail Wakefield and Warrington by six points with only three games remaining.
