Eduardo Vargas is on the brink of moving to Premier League new boys QPR as Harry Redknapp looks to improve his attacking options after a disappointing opening day defeat to Hull City.

Chile forward Vargas has been on loan at Valencia from parent club Napoli and the Italians are now willing to let the 24-year-old leave on another 12-month deal, with QPR emerging as the favourites to land him.

The Times reports Vargas will undergo a medical at the west London club tomorrow ahead of his loan move, having rejected the chance to link up with fellow South American Gus Poyet at Sunderland.

He made 17 appearances for the La Liga club last season, scoring three goals, and scored the first of Chile's two goals against Spain at the World Cup to help eliminate the then reigning world champions.

He will join compatriot Mauricio Isla, who joined the Hoops on loan from from Italian side Juventus.

Vargas's loan move comes after manager Harry Redknapp admitted his squad might not be as strong as it was last season in the Championship.

"We had loans last year, so it was a strong squad with lots of numbers. Now there's not so many numbers," Redknapp said.

"I'm happy defensively, but it's in midfield we're short. If you want to play three in midfield, you need more than just three.

'I've only bought four players, we've not gone mad, have we? We let eight loan players go that were here last year. And then we let six or seven go so that's about 13-14 players out."

QPR chairman Tony Fernandes has so far forked out £8m for Steven Caulker and £6m for Jordon Mutch, both of whom arrived from relegated Cardiff City.

Redknapp brought in Rio Ferdinand as well as Isla but has seen 14 players either sold or let out on loan.
