Only 14 players have played for Manchester United and Manchester City since the Second World War.
Denis Law and Carlos Tevez directly swapped red for blue. Others have represented both at academy level but failed to break into the first-team at either, as Frederic Veseli did. Brian Kidd even played and coached for the senior sides at both clubs.
Jadon Sancho is the most recent example of a player representing both sides of Manchester after signing for United from Borussia Dortmund four years after leaving City. Jeremie Frimpong could become the next if reports prove to be true.
