He's nowhere even close to Sanabria's level. He wasn't back when they both played in the youth ranks and that hasn't changed. He'd actually be benched at Gijon. Lol.
Sanabria is such a sad case, the best CF forward in La Masia, left for first team action only to end up in Roma's B team then loaned. Essentially exactly where he'd have ended up had he stayed with Barca (Especially when you consider Halilovic was his replacement IIRC). Now though Halilovic is making waves and will likely be back at Barca next season, if Sanabria were to show potential he'd be headed to a 2nd(3rd?) tier team.
OT: Sandro should go to a mid-low level spanish team, they seem to work really well for our guys, first Rafinha and now Halilovic.
