Benfica are likely to reject Real Madrid's opening offer for Rodrigo Moreno.

Real sold Rodrigo to Benfica 18 months ago for €6 million and are prepared to offer double to bring him back, says Sport.

However, with no buy-back option now existing, Benfica have referred Real to Rodrigo's new €30 million buyout clause.

News that Real are eager to re-sign Rodrigo has unsettled two of their Castilla prospects, Alvaro Morata and Juanlu, who had both hoped for a chance to prove themselves in the first team in 2012.
