According to Sukazi, Tower was also a wanted man in the PSL, but he refused to disclose the names of the teams that showed interest in his client.
The 26-year-old defender was linked with African champions Mamelodi Sundowns during the January transfer window as talks between him and Chiefs appeared to take longer than expected.
"Eric was wanted by many teams. Some of those teams were South African clubs and others were from Europe," Sukazi told Isolezwe.
"In Europe, he's wanted by teams from Russia, Croatia and Sweden. We rejected those teams because their offers were not good enough," he said.
"It doesn't make sense to go to Europe when the money is also not that good only to return home after a season or two. Their offers were not good enough, and for that reason we opted to renew with Chiefs," Sukazi revealed.
Sukazi said there was never a doubt that Mathoho would renew his contract with Chiefs, saying they showed that they still needed him by offering the South Africa international an improved deal.
"Chiefs showed that they still needed him by giving him an improved contract, and that is why he never thought twice about signing the contract," he continued.
"He's happy at Chiefs and he still wants to achieve more. If there's an opportunity for to go abroad, Chiefs won't stand in his way - they confirmed that to us. You don't need a clause for things like that; everything depends on the kind of relationship you have with that particular team," Sukazi added.
