That's not the logic I've used. It's your retard view of logic.
I've simply pointed out that Downing was Villa's best player last season, whilst Valencia was far from being Man. Utd's best player. This of itself does not necessarily make Downing a better player than Valencia. What it does do is illustrate the point that a fair few Man. Utd fans have this delusion that most of their squad players are better than all of the best players in the starting XI of all the non-top 6 Prem teams.
Most Villa fans would rather see Downing stay than Young if they're forced to choose. Yet Fergie is busy pursuing Young, whose arrival will likely dampen Valencia's standing in Man. Utds pecking order. The pursuit is understandable, since Young is a pretty good player whose contract situation means that Villa must perforce sell now or risk losing him later for nothing.
My view - not based on your retard view of my supposed logic - is that Downing is a better player than Valencia. I'm not surprised that Man. Utd fans take exception to this view.
