They have become two of the best sides that the Premier League has ever seen, with Man City and Chelsea hoovering up a number of titles over the last decade or so.
Between them, they have scooped eight Premier League titles, and have broken plenty of long-standing records along the way, with both sides taking a part in the evolution of football on these shores.
Of course, none of this would be possible without having some great players, and over the course of the Premier League era, these two have certainly had their fair share of top talent among their ranks.
So as we like to do here at The Football Faithful, we have put together what we think is the best ever combined XI between these two sides from the Premier League era. Take a look, and let us know what you think.
