Northamptonshire head coach Darren Lehmann says there is “no problem” with his side’s form in the T20 Blast after progressing to the quarter-final.

The Steelbacks lost three of their final four Central & West Group games, including a five-wicket defeat to Warwickshire on Sunday.

But Northants still comfortably topped the group to secure a home tie in the last eight against Gloucestershire on Wednesday after picking up more wins (9) and more points (36) than any other side in the competition.

“It’s been excellent, we’ve won nine games, lost two of the last three and that can happen,” Lehmann told BBC Radio Northampton.

“It’s chopping and changing sides to make sure everyone’s getting a run out just in case of an injury. We all got through pretty well.

“We normally play a pretty settled side all the time. We got an advantage to do that in the last few games because we played so well. The results didn’t go our way.

“There’s no problem. It’s not going to change how we want to play come Wednesday.”

Northants will be aiming to reach a second successive T20 finals day when they host Gloucestershire, who finished third in their group and eight points behind.

Despite facing the bottom seed, Lehmann says the group stage results count for nothing now.

“Come Wednesday, results don’t matter. It doesn’t matter where you finish on the table,” the former Australian international added.

“It’s how you play on Wednesday in front of a big crowd. We’ve just got to win that game and then you work on the next game.

“It’s pretty much how we’ve planned the whole Blast campaign to be perfectly honest.”

The Steelbacks have won the T20 Blast title twice – in 2013 and 2016 – but have not reached a final since their last success 10 years ago.
