The soon-to-be out-of-contract defender has failed to make a competitive appearance for the club since his 2011 arrival.
Khumalo, 28, made a £1.5 million move to Tottenham from Supersport United in 2011 after impressing for hosts South Africa at the 2010 World Cup, where he scored in their 2-1 defeat to France, but has since failed to make a single senior appearance for the club.
The centre-back has had loan spells at Preston North End, Reading, Greek club PAOK and Doncaster Rovers since arriving at White Hart Lane but a Spurs debut has continued to elude him.
The former Bafana Bafana captain has been appearing for the club’s Under-21s since returning from a damaged knee cap, which left him sidelined for six months, but his contract is set to expire in the summer.
Spurs are still to show an interest in renewing his deal but agent Glyn Binkin hasn’t committed to a summer exit at this point, suggesting that the Premier League club could keep his client.
“His contract is up in June but we haven’t had any discussions regarding what will happen in future,” he said. “But they have an option to keep him if they want to and we will see what happens in future.
“Lately he has been playing in Under-21 because they do allow overage players. But it’s a competitive League and it’s good for him. The club is happy that he is back from injury and happy to have him back.”
Nevertheless, with Mauricio Pochettino having Jan Vertonghen, Eric Dier, Federico Fazio, Vlad Chiriches and Younes Kaboul all available to him amid their push for their Champions League place, there’s little chance that Khumalo will get a chance to prove his first-team worth over the final stretch of the season.
His signing seemed a strange one in the first place, regardless of the reasonable transfer fee, and it now looks like Spurs fans will never even get a chance to see him in competitive action for their side, despite his agent’s assertions.
