West Ham have signed Jack Wilshere from Arsenal on a three-year deal.
The 26-year-old joins Manuel Pellegrini's Hammers after leaving the Gunners following the expiry of his contract.
Born in Hertfordshire, Wilshere grew up in a family who supported the Irons and he expressed his delight at completing the 'special' move across London.
He told the club's official website: “Many people know that I’ve had a special bond with this Club growing up.
“People will have seen the picture of me in a West Ham shirt and I’ve got good memories of my childhood supporting West Ham, watching them at Upton Park. It feels good and of course my family and a few of my friends are West Ham fans so everyone’s buzzing."
Wilshere, who won the FA Cup twice with Arsenal and has 34 England caps, is set to fly out to Switzerland to link up with new West Ham manager Manuel Pellegrini's squad at their pre-season training camp.
West Ham director of football Mario Husillos added: "Manuel and I identified him as a target as soon as we joined the club and we are delighted to have succeeded in securing Jack's signature above a number of other teams."
Five things you may not know about Jack Wilshere
Many old Irons
Wilshere grew up in a family of West Ham supporters and admits to being a Hammer himself in his youth.
Recalling his childhood memories, he told the Daily Mirror: "My first game was against Coventry, in 2000, (Paolo) Di Canio scored a hat-trick."
Wilshere said he "looked up" to Di Canio and will now no doubt want to emulate the sort of relationship with supporters that the charismatic Italian had.
Golden goals
Wilshere was awarded the BBC's goal of the season award in back-to-back seasons during his time at Arsenal.
He finished off a wonderful, flowing team move in a victory over Norwich to claim the 2013-14 accolade.
He would retain the honour following his half-volley from the edge of the box against West Brom on the final day of the 2014-15 campaign.
Guard of honour
While several serious injuries have left the debate rumbling about just how good Wilshere is, or could have been, he has a long-term admirer in Pep Guardiola.
The Manchester City boss has always spoken about how highly he rates the midfielder and said only last season: "I remember in Barcelona and that year we played Arsenal. He left a massive impression when he came. A high, high level. He's quality, he's smart and has the quality on the ball."
Guardiola holds Wilshere in such a high esteem that he was linked with a move for the former Arsenal man after taking the reins at the Etihad Stadium.
Who you gonna call?
Wilshere has revealed on more than one occasion that he considers former Manchester United and England man Paul Scholes to be the best midfielder the Three Lions have ever produced.
It is for that reason Wilshere was determined to hunt down Scholes after he offered some stinging criticism in his role as a television pundit.
Messaging then-England coach Gary Neville for his former team-mate's number, Wilshere later revealed he had listened to everything Scholes had to say and conceded he was "right, in a certain way".
One in 10
Wilshere may have been unable to convince Gareth Southgate he was worthy of a place in England's World Cup squad this summer - but his earlier international pedigree was clear for all to see.
He has 34 senior caps and two goals, but it was at the European Under-17s championships in 2009 where he started to show his promise.
His performances in Germany saw him listed as one of 10 "future stars" from the tournament - Wilshere being the only one who went on to play for his country at senior level.
