So you're more talking about hypothetically in the future he could potentially become effective?
The only run of games the guy had was at the start of last season, trying to supply goals to Soldado - a thankless task - the rest of the season was troubled by injuries and he's hardly played at all in the league this season - so how can you be so quick to write him off?
He would in my opinion be more effective than Lamela, because he'll provide more crosses from the right than him.
