West Ham have signed England keeper Joe Hart on a season-long loan deal from Manchester City.
Hart has struggled to make any impact under Pep Guardiola following the Spaniard's arrival at the Etihad Stadium last summer and was sent out on loan to Torino last season.
With the summer signing of Ederson from Benfica, Hart knew his days were numbered at the Etihad Stadium and was allowed the chance to join another Premier League outfit.
The Hammers beat off interest from Newcastle to land his signature and will have first option on making the deal a permanent one next summer.
Hart, speaking to West Ham TV, said: "It's important for me to play football and to get the opportunity to come here and play is absolutely awesome.
“To be playing in the Premier League for a big club like West Ham, I'm really looking forward to the season.
"I've always loved the club. I think you'll struggle to find anyone, apart from the direct opposing fans around London, who doesn't love the club. It's got something about it, it's got a lot of history and I've always loved playing against West Ham.
"We've moved into London Stadium and we've got Slaven in charge who I've spoken to and I've always enjoyed as a manager.
"He obviously did a good job with Croatia and he's doing a good job here, so to get the opportunity to come here, it wasn't really a hard decision."
Hart will get an early chance to come up against his former club when the Hammers play Manchester City in a pre-season game in Iceland on August 4.
The 30-year-old will then make a return to Manchester for the opening Premier League game of the season when his new side travel to Old Trafford and he is expecting an interesting reception from the United supporters!
Hart added: “I'd like to think I've obviously left Manchester City on loan this season, but the club as a whole, especially the supporters, have always been fantastic to me.
"I'd never change how I feel about that club, as it'll always be a very special club to me.
“It'll be fun to play against them because I'll be banned when it comes to the actual season, while I'm sure Manchester United will welcome me with open arms if I get the nod and start the season away at Old Trafford.”
West Ham will pay a £2m loan fee and put £2.5m towards Hart's wages over the course of his season-long loan.
That will then cover the full cost and mean that City will not have to subsidise Hart's wages during his stint in London.
There is no clause in the loan to make the deal permanent.
The 30-year-old will head straight out to Austria to meet up with his new team-mates at their pre-season training camp.
Hart is keen to show he is still one of the best keepers in the top flight and with the World Cup taking place next summer, he is determined to secure regular first-team football.
Slaven Bilic has been waiting patiently in his attempts to strengthen the squad, but is thrilled that the club have been able to sign one of the biggest names in the top flight.
Hart's arrival is bad news for fellow keeper Adrian, who is now ready to quit the London Stadium and a target for Newcastle and Crystal Palace.
Republic of Ireland international Darren Randolph, who also secured the number one spot for a chunk of last season looks set to be pushed down the pecking order, and is also in the frame to go to the Magpies.
