St George Illawarra coach Paul McGregor has named his mandatory 21-man squad for the Dragons' Round 2 clash against the Parramatta Eels at WIN Stadium, Wollongong this Sunday, March 12.

The only change to last weekend's initial 21-man squad is that back-rower Luciano Leilua replaces Jake Marketo in the Dragons' named reserves.

Following the Dragons' big 42-10 win over the Penrith Panthers last weekend, hat-trick hero Joel Thompson has urged his teammates to stay focused ahead of the Eels clash.

"We have plenty of belief here," Thompson said.

"Everyone was writing us off everywhere we looked. We need to put in performances like that week-in, week-out as well as build on last week."
