Mushekwi – who is on trial with the club – has reportedly impressed the Germans with his aggressive style of play.
But while the club believes the 25-year-old player would be well suited for the tough Bundesliga, they want to conduct further assessments of the striker before deciding whether or not to acquire his services.
"They [FC Nuremburg] have requested for an extension of Nyasha's trials," Mamelodi Sundowns spokesperson Kableo Mosito tells KickOff.com.
"This means that he will only be back in the country on Sunday. It would therefore be premature to comment on whether or not they are considering putting in an offer for him," Mosito adds.
Mushekwi's agent – Ralph Nkomo – says the Germans have expressed a keen interest in roping in the fast Zimbabwean forward into their ranks and are already preparing an offer for Sundowns to consider.
Sundowns – who have turned down previous offers for the player in the past – will only seriously consider a bid in the region of €1 million (R10 million) for Mushekwi's signature.
Meanwhile, Belgian side Standard Liege and Sheffield Wednesday of England have also been monitoring Mushekwi and are expected to table an offer for the forward if the Brazilians do not reach an agreement with FC Nuremburg.
