No, it wasn't that he chose the wrong option, it's that he didn't have the ability to execute the cross. If I can spot this technical weakness, rest assured every scouting report on Lamela will pick it up and reference will be made to it in the opposition team talk: "Show him outside and he won't be able to do us any damage - just keep him away from the 6 yard box - it's only Walker we need to worry about delivering quality crosses from the right".
If Lamela ever whips in a quality cross with his right I will proved to have been wrong.
so now it has to be a cross on his weak foot for him to be any use - one could come to the conclusion you're just picking the things he hadn't shown himself to be great at and building them up as all important attributes or in other words having a unhealthy bias against the lad, ignoring positives and focusing on the negatives...
Scores a few good goals for us ; "pfft come back to me when he smashes in a thunderbolt"
Plays wide and has positive effect; "pfft come back when crosses the ball on his weaker foot"
Creates a variety of chances for his team mates; "pfft they were'nt as intelligent a pass as two of the best ones we've seen from our in form tailisman"
I look forward to hearing about how he can't rifle in a header, hold off 6 defenders whilst doing keepy uppies or recite ancient latin text whilst riding a unicycle in the coming weeks.
