It's hard to see clearly. . . . I only see six signatures from top to bottom, which are: the first row: Nani, the second row: Rooney, Carrick, and the third row: Fletcher, Ferdinand and Edwin van der Sar.

Others can't see clearly whether there are other signatures, but this dress may not be the latest model. Because of the bankruptcy caused by the economic crisis, AIG, the original sponsor of Manchester United, has withdrawn from sponsorship, so the word AIG will not appear on Manchester United jerseys since last season.

I hope these answers can help you
