It's a token gesture, why doesn't Ozil pay a portion of his salary to the 55 people that were sacked by the club?
If you remember Woolwich asked all their players to take a % pay cut around lockdown to keep the general staff employed. I think most players did except Ozil and 1 other, basically they wanted assurances that their money would actually be used for what Woolwich said it would.
Going by how Woolwich have acted I wouldn't trust them that they wouldn't spend the money on a 3rd keeper then sack a load of staff.
