Siwelele have already signed Botswana star winger Joel Mogorosi from Mochudi Centre Chiefs, but according to KickOff.com informants they are again raiding Centre Chiefs.
"Mara left this morning to travel to South Africa so he is going for a trial at Celtic," a source reveals.
Moloi is revered in Botswana after he finished the season as joint top scorer with Mogorosi after both players each scored 26 goals.
Moloi was talk of town recently when he won the Botswana Premier League Player of the Season, Players' Player of the Season and Green Boot awards, raking in P100,000 for his efforts.
A Botswana-based soccer journalist Mthokozisi Dube describes Moloi as a player who is not skilful, but who has a knack for scoring goals.
"He is a box striker and he buries chances, not very skilful but he just knows how to put the ball in the net," Dube says.
