The South African national team have been dismal in front of goal lately, with Pitso Mosimane's men firing home just three times in their last six international fixtures.
However, 2011/12 PSL Golden Boot-winner Nomvethe and runner-up Rodgers, who between themselves scored 33 Premiership goals this season, have both been training with Bafana over the past two weeks as the team prepare for their upcoming 2014 World Cup qualifiers.
And Mphela, who plundered 10 league goals for Mamelodi Sundowns this term, feels the inclusion of the strike duo in the national side will go a long way in helping the country earn their place in Brazil.
"We all know goal scoring has been a problem but I believe with time we will get it right. There is a healthy competition for strikers which is good. Siyabonga Nomvethe and Eleazar Rodgers did very well during the PSL season that just ended and it's good to have them here, we are all hoping they will continue scoring goals even for the nation," said Mphela.
Speaking of Nomvethe, who also scooped the PSL's Footballer of the Year, Player of the Season and Players' Player of the Season awards, Mphela added: "He has been scoring goals, and at the moment is on a high.
"I think he is one of the most confident players in the team, he has the experience as he has been there before so I believe he will bring a different dimension to the team."
Bafana kick off their qualifying campaign against Ethiopia on Sunday, and while the South Africans are expected to come away with a win, Mphela says they will be taking nothing for granted against the footballing minnows.
He said: "As for Ethiopia we are in for a busy afternoon. They have very fit players who run the entire match and will give our defence a hard time, but we are ready for them."
