After a few suggestions I made some corrections on the Manchester United designs. The sponsor was changed into the 10/11 season AON and the black background was removed from the crest (on the red and on the white shirt). The player choosed for this design was not changed because I think Nani is great and he deserve to be on my presentation.
The away kit remained the same, only the sponsor and the crest were changed.
At the Newton Heath style kit changed the shade of yellow (I guess now it's closer to the original one).
A version for the Champions League with the back of the shirt in one colour (as the UEFA regulations require). The collar was changed to black also.
