Rilee Rossouw on the Proteas building momentum for the T20 World Cup: 'The sky's the limit'

Proteas batter Rilee Rossouw has his eyes on helping the Proteas make a proper fight of it at the T20 World Cup later this year.

Rossouw, who smacked an unbeaten 55-ball 96 in South Africa's 58-run win in the second T20 against England in Cardiff, said they're building a more than decent head of steam ahead of the World Cup.

If the Proteas fielded better in the first T20, the series may have taken a different path, but Rossouw chose to take the positive route, saying there's the need to build momentum for the World Cup.

"Everyone wants to play to win a trophy and the Proteas have had a great last year and there's the need to build on the momentum leading into the World Cup," Rossouw said.

"This is not the World Cup, but we're putting in some good performances from an individual and team perspective.

"The sky's the limit now."

They didn't show a lot of it in last year's T20 World Cup, especially after their meek opening loss against Australia.

However, they got better as the tournament progressed, but their lack of self-belief at the start of the tournament cost them dearly.

Rossouw feels he provides an injection of this, but also said doing well at a World Cup will require a collective effort.

"You have to have belief in yourself first before someone else can see it," Rossouw said.

"I do believe in my ability, not necessarily to win a World Cup, because that is impossible. However, I can put in a performance that can help my team."
