Wakefield chairman Michael Carter has admitted his relief at seeing his club retain their Super League status.
Trinity overcame London to seal their survival, at the expense of the Broncos, who drop down to the Championship.
Carter told Sky Sports’ Jenna Brooks: “I’m relieved, but congratulations aren’t what you take out of it.
“I’m sad for London because they’ve been brilliant all year.
“They battered us twice this year and I was really nervous about tonight’s game, but we did enough.
“We know we’ve got to be better next year.
“We’ve got to look forward and be able to cope with injuries and adversity.
“We’ve not had the mental or physical capacity to overcome the injury crisis, which has been serious, but we’ve to find a way to be stronger if that happens again.
“We don’t want to be in this position again.”
Carter rallied support ahead of next season, while promising positive news on Trinity’s stadium development plans.
He added: “Hopefully the 6,000 Wakefield fans at tonight’s match can come to every game next week because I thought they were brilliant.
“And hopefully there’ll be some good news in the next three or four weeks on the first phase of the development plan.”
