Which jersey are you referring to? Is this the 02-04 nike home man united jersey? If yes, then the vodafone sponsors are velvet material right? If yes, then you can simply use gam gajah to stick it back on to the jersey. Simply put gam gajah, press back the sponsors on to the jersey, then flip your jersey inside out (terbalikkan the jersey) and then iron press it for 5 seconds. Set your iron to medium heat.

Don't use gam gajah if the material is PU (thin plastic type) because the acid that is part of the gam gajah will melt it.
