He also knows that the only way to win at the Warriors is to play for 80 minutes, and back each other up.
“We’ve been on the top of the ladder a few times, and haven’t performed so well as to stay there,” said the 34-year-old.
“I think this is a big test for us this week, against Wigan, I’m sure everyone will be up for it.
“I’m sure it will be a tough game and everyone will have to play their best to get the win this week.
“We owe something to our fans for Good Friday. This week we’ll be looking to set that straight, and hopefully give our fans something to cheer about.
“I think we need to work as a team and help each other out, and always have each other’s backs.
“When you’re working with each other for the full 80 minutes then that helps a lot.”
Veteran Paul Wellens has been a solid performer for the Saints this season, and not always at full-back. Although used mainly as a utility player this season, Wellens will be back in his customary number one slot on Friday evening, as Jonny Lomax is out for the rest of the season with injury.
Manu is confident that the experience of players like Wellens will stand them in good stead for the tests to come this season.
“He’s that type of player, you can put him in any position and he’ll do a job for you,” he added.
“We’ve got better depth this year, so anyone who has been missing, the ones who have come in have done the job and done it well.
“We’re on top now, so the aim is to stay there, but we need to take every week as it comes, one game at a time, and we’ll go from there.”
