How much is Nicolas Gaitan valued at? He'd most definitely be worth the investment, if it is somewhere in the 23-25 million Euro bracket. I also think he earns around 1.3 million Euros @ Benfica, so doubling his wages isn't out of the question.
He is somewhat of a poor man's Di Maria. He has pace, dribbling ability, can be deployed as a CM/AM, and primarily as a winger (his original position). Moreover, he is still relatively young @ 26. He is an opportunity that we could (and frankly should) be trying to exploit/look further into.
I can help.
When was introduced Pereyra, Marotta said this :
Eto'o? "Non abbiamo mai parlato di lui. La rosa numericamente deve avere 5 attaccanti e ora ce ne manca uno, oltre all'assenza nei prossimi mesi di Morata. Non mi sbilancio perché il mercato è in continua evoluzione. Siamo alla ricerca di un attaccante di profilo medio".
And this is declaration. A medium profile. Then in the next declation, in the Romulo day for example, he was less specific.
