'Mahoota', who has signed a two-year contract with the Soweto club, hit the ground running on Wednesday when he scored in Swallows' 3-1 League win over Ajax Cape Town at the Dobsonville Stadium.
Tsutsulupa says there is more from where that came from in terms of goals Mashego can score for Swallows.
"Katlego is quality, he has always been. He plays well, he plays for the club. On Wednesday he showed it and we expect more from him," he says.
"I think he also want to do what is best for his career and now he has to perform each and every match. I think he is going to add a lot of quality into our team," Tsutsulupa predicts.
Meanwhile, the Ladybrand-born midfielder anticipates a tight affair when Swallows host Mamelodi Sundowns on Sunday in the second leg of the MTN8 semi-finals.
"The funny thing is even if they score one, and win the match 1-0 they are through (the first leg ended 3-3). So for us doesn't really matter on what happened in the last game, for us it is to concentrate on this one and to give our all, try and defend well.
"I know most people are saying that because we scored three goals away then its advantage to us but I don't think so, because Sundowns have a lot of quality players and most of them play in the national team," Tsutsulupa concludes.
