Bafana Bafana head coach Hugo Broos has been alerted to tie down a talented winger, who is eligible for both Lesotho and South Africa.
Broos received some pressure to call-up Kaizer Chiefs midfielder Gaston Sirino, who is eligible for Bafana Bafana, after he received his South African citizenship last year.
Sirino, a Uruguayan, can turn out for Mzansi, as he has not been capped by La Celeste at senior level.

In a different case, Stellenbosch winger Lehlohonolo Mojela could be lost to South Africa, if he decides to play for Lesotho, where he was born.
"If he continues the way he started, coming off a successful season with Galaxy, he would have been knocking on the door [of Bafana Bafana]," Barker, who is also a Lesotho native, said in an interview on Metro FM Sports.
"Unfortunately, he had a difficult period [with the injury]. He fitted in like a glove on the hand. He just suits the way we play, he suits our style. He scored some crucial goals for us.
"Unfortunately the bad news is that he's had a knee surgery on his ACL, so he's probably out nearly until the end of the season. Probably he will be back maybe the last month or so [of the season]. It's a big blow for us. But he's had a successful (operation) and the recovery journey has started," Barker added.

At 28, Mojela would not wait for long to get an official Bafana cap, with Likuena keen to rope him into their setup.
The former TS Galaxy forward played for South Africa at the 2024 COSAFA Cup but he can still change his allegiance, as he has not played in a competitive game for Bafana.
