“Win the league,” he told the Free Press. “That’s all I’m looking at.

"The way we’ve trained gives me confidence in this team. I think we’ve trained really well, there’s a really good feel around the place.
"We’re looking really good and I think we can do something special this year.”
The last two completed seasons have seen Doncaster knocked out at the semi-final stage of the play-offs.
Beharrell hopes improvement in defence and better discipline can get them over the line this time.
“The discipline is a massive thing for us,” he said. “We’ve talked about that a lot.
“We do give a lot of penalties away so if we can cut that out I think we should be alright.
“Defensively as well, I think we can improve there. We’ll always score points so if we can back our defence and cut out the silly penalties and dropped balls, things like that, I think we’ll go very well.”
Beherall and his teammates will be back on the pitch this weekend for the first time in 14 months.
"It’s been a difficult time – you get out of that routine of going to training – but it’s been the same for everyone I suppose.
"It’s been great to be back among the lads and I’m really enjoying it.
"We’re all looking forward to Sunday and getting back out there again.”
