Willie Peters pinpoints the key area Hull KR must improve in Wigan Warriors admission

Willie Peters has stressed that Hull KR must start defending their errors better after admitting his side had been shown the levels they must reach by Wigan Warriors. The Robins were no match for Matt Peet's side, who produced a superb display to advance to the Challenge Cup final, winning 38-6.

It was a disappointing day for Rovers, who saw their hopes of a return to Wembley emphatically shut down by the defending Super League and World Club champions. Wigan brutally punished the Robins at almost every opportunity, scoring a number of their tries after handling errors. Their opening try came off a penalty, while their third and fourth tries were a consequence of knock-ons. Tyler Dupree barged over after a kick-off wasn't retrieved while the seventh try was after Tom Opacic had been sin-binned.

Peters admitted that it was an area he hadn't been pleased with in recent weeks, with the same issue letting his side down in Doncaster.

"We're a long way off at the moment," Peters said. "I don't think when you break the game down, there were certain parts where we hung in. But we let them in, when we went set for set we looked okay, but when we gave away a penalty or error, we just didn't defend it.

"That's an area we've got to fix up because we're not defending when something goes against us. That's something we pride ourselves on and we've been good at.

"You need to defend errors or penalties. We didn't. That's something we spoke about then. We spoke about it at half-time as well. The last couple of weeks we've probably let too many tries off the back of a compound error."

Peters was keen to praise Wigan, admitting that they were the team everyone else needed to beat.

"We were up against World Champions and they showed they were World Champions for a reason," he said. "They showed that they're the benchmark of the competition, and we know now; we knew before, where we need to get to, but we certainly know after today, that there's still a fair bit of way to get where we need to be."

Meanwhile, Peters admitted that he would be seeking answers on some officiating matters. Rovers felt they should have had a penalty for an alleged 'escort' challenge on Tyrone May when he chased a kick. It wasn't awarded, and Wigan scored from the following set.

"There were a couple of things there," he said. "I just want to get clarification around an escort and what that looks like, there were a couple of things like offside, things in the ruck. But we got beat today by Wigan, who were a far better team. There was some frustration around decisions, no doubt about that. But, we got beaten by Wigan. I just wouldn't like to see decisions in major games impact those bigger games.

"But the referee certainly didn't have any impact on the final score today. As I said, in big games, moments in big games are important. We wanted to start fast, and we didn't. We had something go against us, that I felt went against us, and we didn't defend it. So we need to be better and that's what I'll own as a coach and the players will own. I'd just like to get some clarification on certain decisions that were made."
