Xulu is due back in South Africa today after a week abroad and will resume pre-season training with his Sundowns team-mates.
Sources close to the player inform KickOff.com that the young defender left a lasting impression at the club, who will now table an offer to The Brazilians.
However, Sundowns spokesperson Kabelo Mosito says the club will only comment after receiving an official bid for the defender.
“We are happy that he did well during trials in Russia,” Mosito tells KickOff.com. “We are informed that the Russians were very impressed by his abilities. Let’s see how things progress.
“He will return to South Africa today and will rejoin the rest of the team which is training. There is not much we can say regarding a possible move so we are just waiting.”
Xulu’s agent, Paul Mitchell of Sivuma Sports Agency, believes Xulu has done enough to play for a European club.
