KickOff.com spoke to someone involved in the deal and has learnt that the Sunderland striker is weighing up his options and will make his decision in the next few days.
The former France international has aspirations for one or two more big-money moves to the MLS or Qatar when his contract expires at the end of the season, but the perception of the PSL might mean he is taking a big step down from the English Premiership and potentially risking a lucrative contract elsewhere.
Saha's massive wages are also an issue for Wits, but KickOff.com has learnt that a prospective long-term deal between Bidvest and Sunderland might mean the Black Cats will take care of his salary for the duration of his stay.
Bidvest and Sunderland already have a relationship in the shape of the 'Invest in Africa' programme. The English Premiership club bear the programme's logo on their shirts.
