Marco Silva and Manuel Pellegrini were both brought in to oversee revolutions at underperforming historic Premier League clubs this summer.
But while the Hammers have been busy in the transfer market, spending more than any other Premier League club than Liverpool, Everton have so far only signed Richarlison.
Lucas Digne looks set to follow the Brazilian through the door at Goodison Park but what if that represents the end of Everton's summer spending? Football FanCast has taken a look at some of the potential consequences...
Michael Keane continues to struggle
As much as it's the attacking signings that will get the fans excited, Everton must rectify their ageing defence as a matter of urgency if they are to get to where they want to go.
The arrival of Digne as Leighton Baines' long-term replacement is a huge step in the right direction, and with Seamus Coleman on the other side, bringing in a new central defender to partner Michael Keane is imperative.
Phil Jagielka and Ashley Williams are over the hill and will drag the Toffees deeper and fail to offer enough cover for Keane, meaning that the former Burnley man could continue to struggle.
Failing to land a younger, more athletic centre-half such as linked Marcos Rojo would simply give Keane too much to do and may see his bumpy start to life on Merseyside continue this season.
Sandro gets a second chance to shine
If no further reinforcements arrive at Goodison, the first thing Toffees fans will do is pray that Cenk Tosun does not get injured, because an initial glance at the backup options does not inspire confidence.
Oumar Niasse, Dominic Calvert-Lewin and moving Theo Walcott up front are all options but Sandro has a genuine opportunity to establish himself as a credible striking option.
A £5.2m move for a striker with 14 La Liga goals in 2016/17 looked one of the shrewdest signings of last summer but Sandro's debut season at Goodison was a complete washout.
Still only 23, he has time on his side and a full pre-season should allow him to prove to Silva that a big-money striking recruit isn't needed.
Young players continue to shine
It is tempting to wonder how central Everton's young guns, led by Tom Davies and Mason Holgate, would be to the club's plans if the austerity era David Moyes oversaw was still in place.
The frugality shown by the Toffees in the 2000s gave young players a chance and it is tempting to conclude that the unsuccessful spending spree Ronald Koeman carried out last summer has left the club with a squad disconnected from the fans.
A summer where Richarlison and Digne are the only two recruits would allow the young guns - and the current crop of promising Toffees is an exciting crop - to take on more responsibility.
Everton fans would love little more than seeing some of their own at the centre of the revolution that takes the club into an ambitious new owner.
