For left-footed centre back options, the Tshwane giants are now settled with Suarez and Mosa Lebusa, while Divine Lunga can also play there just like he has done before.
"Regarding Lucas, it is not an easy job for me because we have centre-back options," says Cardoso.
"Of course, Lucas has been doing quite well.
"It is not easy because the style of the game is not the same as South America in Argentina.

Cardoso also responded to questions on another January signing Jayden Adams, whose integration has been smooth as well.
"Jayden is indeed a player that likes to play football.
"He is a very clever player that we need.
"Everybody likes clever players that can manage the ball in the right way and play in the spaces and position on the spaces and manage the rhythm of the game.
