As a collective, the Premier League shelled out an almighty sum of money over the course of the summer window.

The English top flight easily outstripped its 'top five league' competitors, ultimately coughing up a staggering £1.9 billion as they brought in new recruits.

Astonishingly, that figure alone is more than the overall spend of La Liga, Seria A, and the Bundesliga combined.

With the likes of Manchester United, Liverpool, Chelsea and Manchester City securing blockbuster deals, while Nottingham Forest bought themselves an entirely new squad and then some, the total outlay was always going to be high.

In short, it is safe to say that the Premier League is not short on a bit of dough, but which club, based off their most expensive signings in their history, can boast the most expensive XI of all time?

Well, thanks to a brilliant thread from William Hill, we can answer that very question.

There you have it. It may come as a surprise to see that Manchester City don't sit atop the rankings but, considering the amount of money their cross-town rivals have spent trying to catch up to them, United were always going to be first.

However, while their most expensive starting XI might only be third in the rankings, City are still favourites to win the title this year.
