Arsenal have reportedly said they are in for this guy - report came from an interview with Giles Grimandi. http://www.youtube.com/watch?v=UcVsecCGdso He's an Argentian attacking midfielder - likened to Riqeulme. Also further reports of Matias Suarez, Goetze, Podolski, and Hoilett.
Fantastic player. He's very similar to Mata - he can play on either wing but prefers to be played just behind the striker. I really can't see us getting him, he would cost 20M+
