Wakefield Trinity head coach Chris Chester admits he faces a selection headache ahead of Friday evening's trip to face newly-promoted Hull KR.
Trinity were one of last season's surprise packages, and narrowly missed out on a place in the top four, despite being tipped to struggle at the start of the season.
Chester is eager for the team to build on last year's progress, but admits that deciding on his strongest 17 will be tough.
"It has not been easy trying to break down a 27-man squad into 17. Everyone's training well and doing the right things and we've got some really good competition for places. It is a good problem to have," said Chester, who says his players must focus on their own performances.
"The fans will be pumped for the first game back in Super League and there'll be a lot of emotion, but we've just got to focus on the things we do well. If we do that we will give ourselves a good chance."
Leeds were narrow winners against Warrington, while Hull FC were dominant in victory against Huddersfield in Thursday evening's round one fixtures and Chester is eager for Trinity to make a fast start, at the expense of a rejuvenated Robins side.
"It's important to get off to a good start, but all the games are tough," he added. "A lot of teams have improved this year and it's going to be a very difficult opener, going to Hull KR, but we have to go there and make sure we give ourselves a good chance."
Wakefield are 1212/1 to win the Challenge Cup this year.
