Wakefield forward Mikey Sio says the difference between Trinity now and last year is confidence and the belief they can beat anyone on their day.
Wakefield finished on the bottom of the Super League ladder last season and just maintained their top division status with victory over Bradford in the Million Pound game.
This season Trinity sit in eighth spot and take on Warrington on Saturday in the Challenge Cup semi-finals.
“It’s a massive turnaround for the boys,” Sio told Love Rugby League.
“The massive difference I think comes down to our confidence levels.
“When I first came here last year a lot of the boys, I guess their spirits were pretty low. considering their place on the table and 17 losses in a row.
“That’s a massive turnaround now. Chezzy’s brought in a lot of confidence and we’re just feeding off that.”
Sio has made 21 appearances this season and scored six tries. The lock has often been playing at hooker to cover the absence of Scott Moore.
“I’ve been playing there for a while now so I’m not too fazed if I have to back to hooker,” he said.
“But I still prefer playing at 13, getting to run around the pitch with the ball.”
Sio believes Wakefield can knock Warrington off in Leigh on the weekend.
“Definitely we can,” he said.
“We always start strong, we have to just hold it for the whole 80.
“With a side like Warrington with a lot of speed if we complete our sets and control the ball we’ll go a long way to winning the game.”
Sio re-injured his sternum on Sunday against Castleford but said he will be right for Saturday’s game.
“It’s carried on from last week,” the 23-year old said.
“I should be right. I just have to really look after it during the week.”
