Keene spoke exclusively to Goal on Monday, stating that he will join Amatsantsantsa A Pitori ahed of the new 2018/19 PSL campaign.
While Keene admitted to having had good times with the Students, he is looking forward to playing for the Tshwane side.
The English striker first arrived in the country linked with Kaizer Chiefs, but was rejected at Naturena and later signed for Wits a season ago.
“Yeah I am moving on from Wits, I am thankful for the years I spent there. It’s been good times for me and I am happy with what I achieved - the club treated me well but it’s football,” he told Goal.
“I will be joining SuperSport United from the 1st of July and I am looking forward to it," he said.
“I know they had a tough season, they played in Caf and that has affected them with lots of games but they had a small squad," he continued.
“I still believe they have a great team capable of competing and I am sure a new coach will come in and stabilise the team to challenge for trophies," he acknowledged.
“For me it is a new start and for the team because we have to focus on the new season, but I have to thank Wits, they have been great for me, they have been been awesome,” he said.

“They are good guys, players such as Dean Furman are working hard for the team and I am hoping to do well for them,” he added.
“I know theycame under heavy criticism, but they are family men as they worked hard for the club and their kids, families," he noted.
“I know Dean is getting married, I will be going there to his wedding, so there was a lot at stake for th guys in their tough season,” he concluded.
Keene contributed in winning the PSL and MTN8 Cup titles in the 2016/17 campaign as well as the TKO trophy in the 2017/18 term, but they finished 12th.
