Real Madrid want to milk Arsenal for their player to fund Suarez’ move:

Alvaro Morata is sheer talent and is often given comparisons to the great Raul. He was linked with Arsenal for 1 year now but suddenly his destination seems to be The Old Lady, Juventus. The reason for U-turn in the saga is not unknown to anyone as we all know Arsene Wenger demands for value for the price. If the player is worth 20m and the club is demanding 21m, Arsene Wenger will probably cancel the negotiations.

The Bianconeri are said to be locked in negotiations with Real Madrid at the moment for the 21-year-old, who has decided Turin is his choice alternative to the Spanish capital.
But the details of the deal are yet to be ironed out, with each side having their own motivations. Juventus are interested in taking Morata on loan with an option to buy, presumably to have a first-hand look at his talents before splashing the cash.
Meanwhile, Real Madrid want €20 million up front for the young striker, with a buy-back clause inserted into his contract so he could be recalled as a fully matured player.
And according to Sky Sports Italia’s Gianluca Di Marzio, the Santiago Bernabeu outfit want the lump payment to help out with another piece of business only to cover part of the massive cost of purchasing of Luis Suarez from Liverpool. If Luis Suarez gets to Real Madrid somehow the Los Blancos will have their next Galactico without a shadow of a doubt.
