As well as taking a number of notable scalps home and away, including a historic treble over Liverpool, Slaven Bilic has reinvigorated the East Londoners and with stars such as Dimitri Payet and Manuel Lanzini, the Hammers are playing the 'West Ham way' once more.
The Irons have officially enjoyed their best ever season in the Premier League era and have a positive goal difference for the first time since 1986.
Bilic also masterminded a fitting and thrilling 3-2 comeback win over Manchester United in the last ever game at Upton Park.
Big summer ahead
With that and the big move to the 60,000 seater Olympic Stadium this summer speculation has been rife about new additions to Bilic's squad.
The Hammers have been linked with big bids for the likes of Lyon star Alexandra Lacazette, Bournemouth's Callum Wilson and Liverpool's Christian Benteke to name but a few.
Meanwhile, as many as eight players deemed surplus to requirements at the club have been linked with exits.
And now Jack Sullivan has posted what will dictate the club's transfer business this summer in a post on social networking site Twitter.
How many players will West Ham sign?
When asked by a supporter how much the club were likely to spend this summer, Sullivan said: "Depends on outgoings."
He then went on to suggest the club will be busy when asked how many players the Hammers might sign.
"A decent number I reckon," he added.
Big squad needed
With Europa League football potentially adding an extra 20-odd games to West Ham's fixture schedule, Bilic will need a big squad.
Jack's dad David and his fellow co-owner David Gold have built what is regarded one of the club's best team since their title challenging 1986 side.
But with the club clearing out the deadwood this summer additions will be required in a number of positions.
To that end the Hammers have already added midfield utility man Havard Nordveit to their ranks while Manuel Lanzini's loan has been made permanent.
