Faf du Plessis has committed himself to the T20 captaincy, even though the next World T20 will only be played in four years’ time.

During an arrival press conference in Johannesburg on Tuesday, Du Plessis said he was still keen to play T20 cricket for South Africa and captain the side.

‘The wrong side of 30 would be over 35. I am 31. That’s the right side of 30 and see myself playing a big role,’ Du Plessis said.

‘I haven’t thought of stopping playing T20 cricket. I feel my performances speak for themselves. I love captaining South Africa. I think some of the players won’t be there in four years. But there won’t be a lot of T20 cricket in the next while.

‘So we can look at it in terms of a few younger guys coming through and building for the future. It’s impossible to look four years ahead. It’s an incredibly long time but for now I am loving playing T20 cricket and loving captaining South Africa.’

Du Plessis was fined 50 per cent of his match fee on Tuesday for breaching the ICC Code of Conduct during his side’s final match against Sri Lanka in the World T20 on Monday.

Du Plessis was found guilty of ‘showing dissent at an umpire’s decision during an international match’.

This is the second time within a 12-month period that du Plessis has been found guilty of a Level 1 breach. In October 2015, Du Plessis was fined 15 per cent of his match fee for violating Article 2.1.5 during the fourth One-Day International against India in Chennai.

If du Plessis is found guilty of a further breach of Article 2.1.5 within 12 months from the first offence last October, it will amount to his third offence and, as such, he will be suspended.
