Crompton said: “We’re nice and healthy, which gives me a few selection headaches. I’ve got all my key players available.”
He added: “We know we’ve got a big test this week, and I’m sure Workington will give us a very physical game.
“When you get to the play-offs, the majority of these fixtures are very tight. It can often be a piece of individual brilliance that wins you the match, and I think I’ve got a group of players that are capable of that.
“However, hopefully it won’t come down to that. I’d like to think that the team performs to its full ability and makes things a bit easier.”
Workington coach Gary Charlton said: “We’ve gone off the boil in the last two or three weeks. I think the boys thought the job was done after they got a bonus point at Hunslet.
“I expect a big improvement from this week, and they’ve been told that in very clear terms.”
On Blackpool, Charlton added: “Martin Crompton has some very good players in his squad. I’m expecting them to play some good rugby against us.
“They’ll throw the ball about and try to get us going backwards, but we’ve had a couple of close games against them this year. If we play to our potential, then we’ll give them a run for their money.”
