Hello everyone, My apologies if this has been asked an answered before, but I'm going to be ordering a USMNT jersey from their site and I want Donovan's. There are two numbers listed for him. #10 and #21. Anyone know the story behind this. During Gold Cup he wore #10 so that's the one I'm probably going to get. Just curious as to when and why he switched and if he still wears #21 on occasion. Thanx!
