If you've watched this transfer window and felt like the biggest clubs keep shopping at each other's stores, you're not imagining it. The likes of Elliot Anderson, Morgan Rogers and Sandro Tonali have all moved for £100m or more this summer, and they share something else: they're part of a growing habit of Big Six clubs raiding their own Premier League rivals.
Here's the human angle for fans of the smaller clubs. Your best player getting picked off by Arsenal, Chelsea or Spurs isn't a one-off anymore — it's becoming the norm.
The numbers behind the trend
Since summer 2016, the Big Six (Arsenal, Manchester City, Liverpool, Manchester United, Chelsea and Spurs) have spent £2.8bn on players from non-Big Six Premier League clubs, according to Sky Sports. And it's speeding up. Last season's £647m was the highest figure on record, and this summer already sits at £420m.
Zoom out and the whole league is trading with itself more than ever. Total spend on intra-Premier League signings hit £1.29bn last season — the highest ever by a wide margin. The share of all transfer money going on players already in the division has climbed from a record low of 14 per cent in 2018/19 to 41 per cent this summer so far.
The reasoning is simple enough. Clubs want tried-and-tested players who've already proven they can handle the league, cutting the recruitment risk. The catch is that security now comes with a hefty price tag, with the average top-end signing costing £68m.
Chelsea, the hub of it all
If there's one club driving this, it's Chelsea. They've spent a staggering £862m on players from other Premier League clubs since 2016, the bulk of it since the BlueCo takeover in 2022.
The single busiest corridor is Brighton to Chelsea, worth £263m since summer 2016. Chelsea have also pulled £222m worth of players from Leicester and £156m from Aston Villa — with Alejandro Garnacho heading the other way on loan this summer.
It's not all one-directional, either. Chelsea lead the way on selling to league rivals too, with £683m recouped since 2016/17. For clubs outside the elite, selling to the big boys has become one of the fastest routes to financial headroom under the Squad Cost Ratio rules.
Who's spending this window
So far this summer, Spurs top the table as the biggest spenders with £237m, followed by Chelsea (£203.5m) and Manchester City (£129m). Six of the top 10 deals this window are intra-Premier League moves — that's before you even count Mateus Fernandes' £85m switch from relegated West Ham to Spurs.
For bettors, this matters more than it might seem. Squads getting reshuffled between rivals changes how the top of the table might look, and the outright title, top-four and relegation markets tend to move as these deals land. Whether a club has strengthened by buying proven Premier League talent — or been weakened by losing a key man to a bigger rival — is exactly the kind of thing that shapes those prices heading into the season.
The direction of travel is clear enough: more Premier League money is staying inside the league, and the Big Six are increasingly finding their next signing a lot closer to home.
