Former Tottenham striker Jermain Defoe says he hasn't been short of offers since leaving Rangers.

Defoe, who turns 40 in October, had his Rangers contract terminated last week.

Defoe told talkSPORT: "The phone has been going mad. When the phone's still going at 39 that's a good thing.

"I've got a few options.

"It's well documented that the Sunderland option is there."
