Dolly was speaking ahead of South Africa’s 2019 World Cup qualifying game in Praia on Friday night against Cape Verde.
After two rounds of qualifiers, Burkina Faso and South Africa both have four points, Senegal have three, and Cape Verde are yet to register a point.
A recent AFCON qualifying win over Nigeria has filled the Bafana camp with confidence says Dolly, who believes the current national side under Stuart Baxter is shaping up nicely.
“It all started in Nigeria and we are really getting used to each other. We have a good balance of experience and youth and we work for each other.
“There is lots of vibrancy in the camp and that is what is needed when you go for such assignments,” he told SAFA media.
The former Mamelodi Sundowns and Ajax Cape Town player is however wary of the threat posed by the Blue Sharks in Friday’s match and in the return game in Durban on Tuesday.
“All games we play are critical but this one on Friday is probably one of the biggest because we all know what a win will do to the rest of the campaign,” the Montpellier midfielder pointed out.
“We are playing away from home and the fact that Cape Verde have nothing to lose, they can be tricky customers; just to spoil the party.
“But we are well prepared for the task at hand. We just need to tackle this game the way we did against Nigeria and the rest will fall into place.”
Friday’s match at the Estadio Nacional kicks off at 20h30 SA time.
