When looking back over 30 years of the Premier League, it might feel as though transfers between the Big Six -- Arsenal, Chelsea, Liverpool, Manchester City, Manchester United, Tottenham Hotspur -- are a rare occurrence, but they are not quite as rare as you might think.

Up to and including Oleksandr Zinchenko's switch from Manchester City to Arsenal this summer, there have been a total of 80 moves directly from one of that clutch of teams to another since the league's inception in 1992.

However, there has never been a single player to move directly between rivals Manchester United and Liverpool in all that time. In fact, you have to go all the way back to July 1964 to find the last senior professional player to do so, when Manchester-born forward Phil Chisnall left United after 13 seasons to join the Reds in a deal worth around £26,000.

Of course, the Big Six as we know it today has not always been that way: Chelsea were never title contenders before Roman Abramovich's 2003 takeover, and City similarly were catapulted into the modern elite thanks to Sheikh Mansour's investment in 2008. Tottenham, meanwhile, have yet to match the achievement of Leicester City or Blackburn Rovers by winning the title since it rebranded as the Premier League, so much of their current Big Six status is based on them being regular top-four finishers and Champions League participants over the past decade or so.

We've gone back and reviewed every single deal struck between clubs in what we now know as the Big Six -- including loans and free transfers -- since the summer of 1992 and ranked them by how successful they were.

Let's start with three signings that happened this summer, and are therefore ineligible to be ranked here:

Gabriel Jesus, Man City to Arsenal, July 2022, £46.9m

It's far too early to assess Jesus' transfer to Arsenal, but Gunners' fans will be pleased the club have landed an experienced Premier League striker who provides more than just cute flourishes around the penalty area. With 95 goals in 236 games for City, Jesus is bound to add cut and thrust to an attacking line which has looked more than a little blunt in recent years. For their part, City have lost a talented player, albeit one who was often underused throughout his six-year stay at the Etihad, though now they have Erling Haaland to fill the void.

Raheem Sterling, Man City to Chelsea, July 2022, £47.5m

Again, we can't judge Sterling's impact at Chelsea yet, given he has only just arrived. But the England winger is only 27 and may not have even reached his peak yet, so it stands to reason that he will shine at Stamford Bridge. City's wealth of options up front saw Sterling slip out of favour at the Etihad last season but, despite being left out of some of the club's biggest games, he still chipped in with 17 goals in 47 games. City have almost certainly strengthened one of their rivals by allowing Chelsea to take a relatively young, highly adaptable, world-class forward off their hands for a decent fee as his contract was due to expire in 2023.

Oleksandr Zinchenko, Man City to Arsenal, July 2022, £30m

Zinchenko first moved to Man City in July 2016 as a promising 19-year-old midfielder but adapted to become a left-back and made most of his 128 appearances for the club there. While he hasn't always been directly involved, he still won four Premier League titles, an FA Cup, four League Cups and reached the Champions League final, in which he played the entire game. Arsenal know they have still signed a seasoned player who is vastly experienced at international level. He is Ukraine's youngest-ever goal scorer, beating the record previously held by superstar striker Andriy Shevchenko, and is also the youngest player to captain his country in an official competitive match.
