The father of Ji-sung Park admits QPR's struggles this season have convinced his son to hang up the boots.

The 32-year-old has struggled since signing from Manchester United in a £2million deal last summer and is ready to call an end to his career even if QPR avoid relegation from the Premier League.

His father Sung-jong Park said: "Nobody knows the future; maybe he could play one more year with a new team after next season. But I think [Ji-Sung] has made his mind up to retire. He thinks he's played enough.

"He's never had times like this with PSV Eindhoven or Manchester United. My son has had difficult times at QPR this season; it was a new experience to him.

"Ji-sung said it's difficult to keep his feel for the game as his playing time is inconsistent, but he doesn't have any hard feelings."
