Heaton said: "We have a game in hand on the majority of the teams. We are two points from 16th place.
"At the time lockdown happened we were in a difficult period. We had a few tough results and the performances hadn't been up to scratch really. The break came at a good time for us.
"We certainly have a lot of ability in the squad. We have shown on so many occasions that we can do it and put it all together.
"I am very optimistic - I was optimistic anyway because it was so close - but even now I'm hoping we will gain an experience in this spell on what we have been doing so we can go back, finish the season strongly and finish on the right side of it.
"We have certainly got more than enough ability to do that."
