Sainsbury's Chinese club Jiangsu Suning have completed their Super League season for 2017, so the defender opted to utilise the opportunity to get a long-term issue resolved.

The 25-year-old tweeted a selfie in hospital with a smile and thumbs up after the surgery.

It isn't fully clear what Sainsbury's surgery was on, however given the caption it is likely the groin problem which troubled him in August and September.

The ex-Internazionale defender also suffered a hamstring injury in Australia's final 2017 Confederations Cup match against Chile, which left him on the sidelines for weeks afterwards.

Speaking to Fox Sports after Australia's World Cup qualification, Sainsbury said: "I'll be staying around here.

"I've had problems with my body lately so I'm going to go in for surgery.

"It's been about six months coming so finally I can get it done and get it to rest."

Sainsbury missed the 2014 World Cup squad after suffering a knee injury when he landed on a sprinkler on his debut with former Dutch club PEC Zwolle.
