They are known to be the richest club in the EPL, so I don't know why they are pleading for Manchester City to support them by accommodating their players in the flight.
I really thought this was a joke until I started seeing it from different news websites. It is a huge embarrassment to Manchester United trying to shift their responsibility to their rivals to carry. If Manchester United want their players in the Ballon ceremony, they should be able to sort the arrangement to have them there. Manchester City did well refusing because this kind of favors are often required again if you oblige with the first, that is if they had agreed, Manchester United will most certainly ask again next time.
