West Have have shown off their newest recruit Pablo Fornals to the world, decked in their 1980's inspired new kits after making the Spaniard their third signing of the summer.
The midfielder has signed a five-year deal in east London for a fee believed to be €27m and will join up with his new teammates after the UEFA Euro U21 championships in Italy.
The capture of Fornals adds to the signings of free agent goalkeepers Roberto and David Martin to act as understudy to Lukasz Fabianski in between the sticks and we've seen them modelling the new keeper kits.
European football is the target next season, top ten was the minimum this campaign, and those European ambitions is something that Pellegrini himself wants to achieve as well as being handed the target by the board.
The Hammers spent €27m on Fornals which doesn't leave them a lot to play with. Pellegrini has already moved on Edimilson Fernandes and Lucas Perez from the squad, while Andy Carroll, Samir Nasri and Adrian have also been released.
But what squad numbers could be available to any potential new arrivals this summer? Those of you who pre-ordered kits will have started receiving them this week or next and obviously, we all want to know what names and numbers we can get on the back of the brand new replica shirts we've all bought.
Free numbers
9 - Andy Carroll's number for the last six years, he will be released on July 1 after his injury-plagued stay in the capital so the Hammers could well have a new number nine come the start of the 219/20 campaign.
13 - Was occupied by former number two stopper Adrian but, like Carroll, he will be released in July. 13 is unlucky for some though...
18 - Samir Nasri will depart the club after an unsuccessful six-month stay in east London. He followed such luminaries as Emmanuel Pogatetz and Julien Faubert to wear the number 18.
25 - this number has been vacant for a year as the last person to wear it was former goalkeeper Joe Hart when he was on loan at the Hammers for the 17/18 campaign.
27 - Lucas Perez's old number at the Hammers. The striker has been sent packing to Alaves for around £2.5m and his number 27 is now available for someone to pick up. Marko Arnautovic had this number for all of a couple of days before Sofiane Feghouli left the club and the Austrian took his number 7 shirt.
28 - here's a throwback for you. The last West Ham player to don the number 28 was striker Jonathan Calleri, who flopped in east London in 2016/17. Roger "The Relegator" Johnson also wore the 28 and it was Manuel Lanzini first squad number too.
29 - It was Toni Martinez's number but he has been released by the club so the number 29 is available for anyone who wants it this summer.
31 - This number belonged to Edimilson Fernandes but the midfielder has now been sold by the club as he has joined Mainz for around £8m.
36 - the last player to wear the number 36 in the first team was Domingos Quina and he only used it once. Other players to wear 36 include Wayne Bridge and Blair Turgott.
Potentially available if players leave
12 - Jordan Hugill currently owns the number 12 shirt but he's highly unlikely to be at the club come the start of next season . Also worn by play-off final hero Ricardo Vaz Te.
22 - this number is currently owned by Sam Byram and previously was worn by Angelo Ogbonna. Byram is third in the pecking order at right back in east London.
17 - Javier Hernandez's number. The Mexican could leave the club this summer if the right offer arrives. Gokhan Tore wore it before Chicharito as did, erm, Benni McCarthy,
14 - Pedro Obiang wants to leave West Ham and if they grant his wish then his number 14 shirt will be available for a new arrival. The former number of Radsolav Kovac and Ravel Morrison too.
