England's T20 series defeat against South Africa 'a line in the sand moment'

England's white-ball coach Matthew Mott said the Twenty20 series defeat to South Africa was a "line in the sand" after they ended the home summer without a limited-overs series win for the first time since 2013.

The 90-run loss in Southampton on Sunday gave South Africa a 2-1 win, raising concerns about England's form heading into this year's T20 World Cup in Australia.

Since Eoin Morgan's shock retirement from international cricket in June, India have beaten England in both limited-overs competitions while the ODIs with South Africa ended level following a washed out finale in Manchester.

"It was disappointing. I thought we put ourselves in a good position to win the series and we'll have to take a lot out of that game," said Mott, who took charge in May following Chris Silverwood's resignation.

"I've just spoken to Jos [Buttler] very briefly and this is a line in the sand moment for the team."

England travel to Pakistan for seven T20s starting in September followed by three games against Australia, before opening their World Cup campaign against Afghanistan on October 22. However, the Three Lions will be worried about their loss of form in white-ball cricket, even as their Test team has started to turn things around under the new leadership of Ben Stokes and Brendon McCullum.
