Manyama has spearheaded City's sensational debut season with 12 goals and five assists in topflight competition, earning a Bafana recall for the upcoming friendlies with Guinea-Bissau and Angola.
"I'm not thinking too far ahead and I always think of the next game," said Manyama, who last featured for Bafana in a friendly against Malawi in 2015.
"For me it's one week at a time and one game at a time. Yeah, we'll see at the end of the season what happens.
"But having said that, every game there's always pressure and there's never an easy game. For me I think I've been around long enough to know how I must approach games.
"Look, games are never the same and even though they are not the same I prepare myself in the same way for each and every game.
"We take games very seriously. So for me it's no pressure and it is just about going there and enjoying myself. And just like the coach [Owen da Gama] said, we obviously have to work hard and try to improve each and every game."
While Manyama admits he is enjoying arguably his best season, he pointed out he nearly won the league with Ajax Cape Town under Foppe De Haan in 2010/11. The Urban Warriors were pipped to the post by Orlando Pirates.
"I think individually, yes I'd say it has been my best season," said the 26-year-old.
"But I think in terms of a team I think I also had a great season with Ajax Cape Town that came second.
"We had Thulani [Serero], 'Tyson' Thulani Hlatshwayo, but individually this has probably been the best so far."
Bafana will host Guinea-Bissau at Durban's Moses Mabhida Stadium on Saturday (15h00) before tackling Angola three days later in East London.
Kaizer Chiefs goalkeeper Itumeleng Khune will captain the national side in both matches.
