Lehmann tells Northants to concentrate on themselves ahead of crunch Derbyshire date

The County entertain Derbyshire in their final home game of the campaign on Tuesday (Sept 15), before heading to Lord's on September 24 for the last action of the summer.

As it stands, second-placed Northants hold a slim two-point advantage over third-placed Kent, who missed the chance to stay in the final promotion spot when they were beaten by Derbyshire last week.

That allowed Northants to leapfrog them thanks to their six-wicket win over Worcestershire at New Road, but it is still to tight to call as to who will be playing top flight cricket along with champions Durham next season.

There are sure to be plenty of twists and turns over the final matches, with Kent having the bonus of both of their remaining games being on home soil at Canterbury - and against the league's bottom two teams in Lancashire and Gloucestershire.

But as it stands, Northants know two maximum bonus point wins will guarantee them promotion, and Lehmann says his team has to concentrate on taking care of themselves.

"We just have to win the next two games, that's all we can worry about, and then we will see where we end up," the Australian told BBC Northampton.

"It is going to be important we play well, especially early on in the games, in innings one and two, and make sure you are in front of the game.

"That is the key for any side, getting in front of the game, especially this late in the season.

"Sometimes it changes and you see teams getting rolled over, but they can then go out and get 400 in the next game.

"For us, it is about saying in the moment and it is really important we start well in the next game on Tuesday."

Derbyshire will arrive at Northampton in confident mood after their win over Kent last week, with the victory being secured with just 15 balls remaining.

They will also be able to call on Pakistan seamer Mohammad Abbas, but Lehmann just wants his team to carry on as they have been, producing all-round team efforts to get the desired results.

"Everybody is chipping in, and that is what you have to be if you want to fight for promotion, everybody has to chip in somewhere," said the head coach.

"We have had really good performances from different people in each and every game, and that is a pleasing thing for me.

"We have a good balance in our side, and at Worcester we have taken 20 wickets again.

"In the last two games we have bowled and fielded really well, and if we had batted well against Durham then who knows where we'd be? But that is past now, and the Worcester game is past now.

"We have got across the line and now it is a case of being ready for another big game against Derbyshire."

Play is due to start at Wantage Road at 10.30am on Tuesday.
