Cornwall are set to name an unchanged side as they face Northumberland in the County Shield final on Sunday.

Cornwall booked their place at RFU headquarters - and in county rugby's top flight for 2009 - after a 43-0 win over Eastern Counties this month.

"The players are delighted and really looking forward to it," said head coach Dave Thomas.

"The most important thing for us was to get back into the top tier of this competition."

We are not going to concentrate too much on their game and just play ours Dave Thomas

"Most Cornish people think this is where we should be, and they expect us to be here, so we are just glad that we have achieved that this season. For us, Sunday is an extra treat for the players," Thomas said.

The Cornwall coach said he rated Northumberland highly - most of their side is drawn from National League Three winners Tynedale who took the title by 29 points.

"We are not going to concentrate too much on their game though and just play ours," he said.
