QPR boss Ian Holloway has confirmed his side are hoping to sign ex-Chelsea striker Tore Andre Flo.
Flo has played in Italy for the past two seasons
But he admits he is not confident on his chances of persuading the 32-year-old Norway international to leave his Italian club Siena.
"He will attract interest elsewhere. To get a player of his quality is a real 100-1 shot," he told QPR's website.
"We've done all we can to persuade him that QPR is a great club, but we fully respect Tore will need to take time."
Flo scored 50 goals in 95 starts for Chelsea before moving to Rangers for £14m in November 2000.
He moved to Sunderland in August 2002 at spent a season at the Stadium of Light before joining Siena.
"We are shooting for the stars here - but there is nothing wrong with trying to bring in the very best players available," Holloway added.
Holloway has already signed defender Ian Evatt, midfielder Tommy Doherty and striker Stefan Moore this summer, while goalkeeper Simon Royce will join on 1 July after his contract at Charlton has expired.
