What are 'friendlies' to honor a player usually called in the UK?
In the UK and Ireland, "exhibition match" and "friendly match" refer to two different types of matches. The types described above as friendlies are not termed exhibition matches, while annual all-star matches such as those held in the US Major League Soccer or Japan's Japanese League are called exhibition matches rather than friendly matches. A one-off match for charitable fundraising, usually involving one or two all-star teams, or a match held in honor of a player for contribution to his/her club, may also be described as exhibition matches but they are normally referred to as charity matches and testimonial matches respectively.
