They travel to Saints with a six point deficit, although do have a game in hand against Widnes, re-scheduled due to Wigan’s trip Down Under for the World Club Challenge.
Speaking in his blog on the club’s official website, Green said: “The pressure is on Saints if you ask me, they are the frontrunners this season and are 8 from 8.
“Their fans expect a big performance and I hear they sold out a long time ago and we are only fourth in the ladder so I feel we are going there a little under the radar.
“We’re heading into the game on the back of five straight wins which looks ok but we’re not happy with our form and want to put a few things right over Easter.
“We’ve nailed it in some big games over the last year and this is another one of them so we know what it takes, plus we went to Wire and did a job on them earlier this season so we need to take that attitude into Friday’s game.”
Wigan have been beaten twice so far in the league this season, losing on the opening day at home to Huddersfield, before falling to a 36-31 defeat at Castleford at the beginning of March.
They host Bradford at the DW Stadium on Easter Monday, before a tough run in May that includes two games against Leeds and trips to Hull, Salford and Huddersfield.
