Parramatta Eels went back to the top of the NRL ladder on Thursday with a 26-16 victory over Wests Tigers in Sydney.

A bruising contest at Bankwest Stadium saw the visitors get off to a flyer when Luciano Leilua powered over the line in the opening minute.

The Eels went behind after just two minutes in last Saturday's 22-18 defeat to Manly Sea Eagles and it seemed another early setback had left them shaken, despite Maika Sivo's 10th try of the season drawing them level.

David Nofoaluma also reached 10 tries for the campaign before a Moses Mbye penalty goal made it 12-4, giving the Tigers a measure of control.

Matters soon unravelled for Michael Maguire's men, however, Reagan Campbell-Gillard's 40-metre charge for the line reducing the deficit before a Mitchell Moses penalty goal levelled the scores again.

The Tigers lost Michael Chee-Kam to a serious-looking concussion and were soon trailing by six at the break, Moses scoring after a superb chip and chase.

Shaun Lane touched down from a Clint Gutherson grubber to stretch the Eels' advantage and Sivo's second effectively sealed the points.

Some quick passing sent Tommy Talau clear down the left to score a consolation, but the Tigers stay seventh in the standings, with the Eels a point above Penrith Panthers after playing a game more.
