Alex Song and Victor Moses among four new West Ham signings
West Ham were the big movers on a relatively placid transfer deadline day as the Premier League club brought in a quartet of new faces - with a fifth arrival still a possibility.
The long-anticipated return of Alex Song on a second successive season-long loan from Barcelona was the first completed deal of the day and he was soon joined by a trio of attacking talents.
Victor Moses also moved on a season-long loan deal having penned a new four-year contract with Chelsea beforehand, with Nikica Jelavic and Michail Antonio signing from Championship outfits Hull and Nottingham Forest whilst Tottenham's Emmanuel Adebayor is still a target.
The 27-year-old Song, who is currently unavailable for selection due to an ankle injury, rejoins after a successful stint last season and the former Arsenal midfielder said another year at Upton Park was a simple decision to make.
"It was a very easy choice for me to come back here and I'm very happy to be here," he told West Ham TV.
"I am very happy. For me it was very important to come back because when I was here I had a great rapport with the fans and the club.
"When I left I didn't know I would come back here. It was not easy but at the end of the day, the most important thing is I'm here now and I'm very happy.
"I feel at home, everything feels at home, for my family too, they're set up very well here."
Nigeria international Moses followed closely in Song's footsteps and will now spend a third year in succession away from Stamford Bridge on loan.
Moses, 24, has previously been at Liverpool and Stoke but would appear to have a future at Chelsea as he signed a new deal with the club before it was confirmed he had moved on a temporary deal across London.
With Hammers boss Slaven Bilic admitting he wanted to add more attacking options, Moses will add much-needed width to the squad and the former Wigan man is looking forward to a spell at Upton Park.
"Delighted to sign a new deal at Chelsea and now looking forward to a good season with West Ham," he wrote on Twitter.
As well as a pair of established players arriving on loan, West Ham also addressed their need for another striker by bringing in the experienced Jelavic from Hull.
The 30-year-old has signed an initial two-year deal at Upton Park, where he will link up again with Bilic after playing for the West Ham boss during his time in charge of Croatia.
The former Rangers forward will now be looking to get back into top-flight action having scored eight goals in Hull's relegation from the Premier League last season.
Jelavic, who underwent surgery on a long-term knee problem earlier this year, admits the lure of playing under Bilic was part of the attraction in moving to east London.
''I've played for Slaven before for the Croatia national team and he is a great manager and a great man,'' he said.
''I am really happy and delighted to be working with him and all his staff again. I am very excited to be signing for West Ham United, especially as it is a big club and I didn't know until a couple of days ago that I would have the opportunity to come here.
The final acquisition, for now, was that of Antonio from Forest as Bilic finally got hold of a player he has been targeting for some time.
The 24-year-old winger signed an initial four-year deal with the club, signing for an undisclosed fee after hitting four goals for Forest in all competitions this season.
''I've worked my way from non-league and finally got to the Premier League to show what I can do,'' the ex-Sheffield Wednesday ace said.
''If the fans don't know me from the Championship, what I bring to the table is pace, power and goals, so hopefully I can do that this season."
A move for Tottenham striker Adebayor has yet to materialise.
The Togo international cannot join on loan due to Premier League rules meaning no other domestic loans can be completed with Moses and Arsenal's Carl Jenkinson already on board.
There is still scope for Adebayor to move to West Ham but Press Association Sport understands he is demanding £5million from Spurs to terminate his contract a year early and the club are not willing to pay such an amount.
