Wellington Paulista completed a loan deal to West Ham, while Stephen Kelly joined strugglers Reading from Fulham for an undisclosed fee.
West Ham have added another striker to their ranks, after the addition of Marouane Chamakh from Arsenal, with Wellington agreeing on a six-month loan deal, with the Hammers having the option of making the move permanent by offering a three-year contract for the Cruzeiro forward.
"I think I can do my best here and I am coming to England to prove to everyone that I am one of the best strikers in Brazil and to get better and better," Wellington, who scored 27 goals for Cruzeiro last season, told the club's official website.
"I am strong, I am a fighter and I can score with both feet. I run a lot on the pitch and I can play as either as first or second striker.
"The pressure will not be a problem for me because I am used to it from my time in Brazil, where the fans were really addicted to the club. The manager also put pressure on the players too, so it will be the same playing here."
West Ham co-owner David Sullivan welcomed his "wildcard" signing. "I'd like to welcome Wellington Paulista to east London and West Ham United," Sullivan said. "He is another exciting player to add to our squad and although he may not be that well known on these shores, he comes with an excellent track record in Brazil.
"His arrival is similar to some of the other 'wildcard' players we have signed before like in Demba Ba and Ilan. They both made significant contributions and if he can match their efforts he will be an excellent acquisition for West Ham United."
Meanwhile, Reading have completed the signing of Stephen Kelly with the fullback penning a two-and-a-half year contract.
Kelly found it difficult to get game time at Fulham, with summer recruit Sascha Riether making the right back position his own. The 29-year-old will now have the unenviable task of trying to get Reading out of relegation trouble.
"I'm delighted to have Stephen here," Reading manager Brian McDermott told the club's official website.
"He has played a lot of games in the Premier League and more than 30 times for his country. He's the kind of player I've been talking about -- someone with great experience, but at 29 still very young in football terms and at a really good stage in his career.
"I know he's going to fit into the dressing room here really well. He's up for the fight, up for the battle, he's hungry, he wants to do well and I know he'll be successful for us."
