UC Sampdoria, who ply their trade in Serie A is another example. They are an amalgamation of two clubs, Ginnastica Sampierdarenese (1891) and Andrea Doria (1895). They merged in 1946 to give us the club that we have today. Therefore UC Sampdoria is just 71 years young, not 126 or 122. So DUFC (1975) are only 42 years in existence, not 98 years that is often erroneously given.
Btw, are there any other cases of this in the League at present, or is DUFC (1975), a unique case?
