We have both to go on with Zaha then, a full pre-season with United and three full seasons of Championship football; it was you who mentioned training sessions. According to you it's inconceivable to suggest that Zaha is first team material based on such evidence, yet above you seem to be suggesting that pre-season + some reserve team or J2 League football was enough to convince Juventus and Dortmund of Paul Pogba and Shinji Kagawa's suitability. You can't have it both ways; either it was ridiculous of Juve and Dortmund to throw Pogba and Kagawa in at the deep end or it isn't ridiculous to suggest that United might do the same with Wilfried Zaha.
