Joint Town coach Gary Charlton said: “We created a lot of chances but we didn’t take all of them. That was what knocked us back from winning the game to losing it.
“Our problem isn’t creating the chances, it’s finishing them.”
On Oldham, he said: “They’re usually a big, physical side that go forward through their pack.
“We’ll be putting out a team that we think can combat that and then hopefully we’ll use our backs on the back of that.”
Oldham coach Tony Benson saw his team beat Gateshead 66-12 last week.
He said: “It was a very good performance. It was comprehensive right across the board.”
But he has warned his side to expect a battle when they travel north on Sunday.
“Workington look very good,” he said. “They’ve put together a team that has most of the best players in Cumbria. They’re going to provide a very stern challenge.”
