Queens Park Rangers have kicked off what is expected to be a last-minute spending spree by signing Yun Suk-young.
The 22-year-old South Korea international joins the English Premier League relegation battlers on a three and a half year deal.
Harry Redknapp, the QPR manager, is also looking at moves for Peter Crouch and Chris Samba before the transfer window closes tomorrow night.
Everton's move for Leroy Fer from FC Twente could be in doubt after a problem with the player's medical.
The English Premier League side had agreed a £8.6 million (Dh49.6m) fee with the Dutch club for the 23-year-old midfielder.
But concerns have been raised following the player's medical on Merseyside which are understood to have caused Everton to look to renegotiate the deal.
Instead of the full fee up front the Goodison Park club wanted to pay a smaller amount with the remainder dependent on appearances and other factors.
Twente have rejected the new terms, leaving the move is in the balance.
Fer missed almost two months of the Eredivisie season after sustaining a knee injury on Holland duty in September.
Everton, who have refused to comment on the situation, are obviously concerned about the long-term prognosis and want to protect themselves against future problems, especially considering the substantial initial fee they were originally prepared to pay.
Joop Munsterman, the Twente chairman, told De Teegraaf: "Everton have additional requirements on the method of payment. Here we do not agree. It's stuck.
"We don't play that game at Twente. They can come up with any demand they wish but we're not playing along with their demands."
Stoke have resurrected their deal to sign FC Dallas winger Brek Shea after originally claiming the move was dead in the water.
The USA international will join the English Premier League side from Major League Soccer, subject to a work permit and medical.
Shea was a spectator at Stoke's 2-2 home draw with Wigan last night and afterwards Tony Pulis spoke of his optimism of signing the 22-year-old.
"I think it is close now, and we are hoping that we can get that deal done in the next day or so," said Pulis. "Brek is a very, very exciting player, and one who we believe could go on to become a very good player for the football club.
"He has terrific pace, a very good left foot and he is capable of scoring goals.
"I believe he has all the tools needed to be a success here, so hopefully we can get the deal done."
Vancouver Whitecaps have signed Daigo Kobayashi, the Japan international striker, in a bid to boost their striking options.
The 29-year-old spent the past two seasons with the Shimizu S-Pulse, and has experience playing in Europe with Greekside Iraklis and Stabaek of Norway.
"We're really pleased that Daigo is going to be joining us," said Martin Rennie, the Whitecaps coach
"He's technically very gifted and he has got an excellent final pass. He can create goals for us and he has got a lot to prove.
"Those are the type of players we want in our squad."
Florian Thauvin has signed for Lille from Bastia - but will remain with the Corsican side on loan for the rest of the season.
The 20-year-old, who had been a transfer window target for Newcastle United, has scored three goals in 19 Ligue 1 games this season.
Lille are thought to have paid EU3.5m (Dh17.2m) for the France under-20 international
Bastia revealed last week that Thauvin had refused to sign an extension to his contract, which was due to expire in 2014, but insisted he would end the season at the club.
Hoffenheim have signed Igor de Camargo from Borussia Monchengladbach until the end of the season.
The Brazilian-born Belgium striker will be asked to help fire the club out of the Bundesliga drop zone.
"With Igor, I hope he can have a big impact in attack," said Andreas Muller, Hoffenheim's general manager.
"I am quite sure that he will play with class and experience in the league and play an important role for us."
De Camargo, 29, has nine caps for Belgium since gaining citizenship, having made his debut in February 2009.
