We have to keep up an extraordinary pace to maintain our position. That they are reinforcing is certainly not a positive thing. I also see the second half of the season as a busy schedule and therefore we must hold a lot of attention."
21.59 GMT: Stoke City will soon loan American striker Juan Agudelo to Dutch club FC Utrecht, according to sources with knowledge of the deal. FULL STORY.
21.38 GMT: Lucas Moura's agent says the Brazil midfielder won't be leaving PSG in January.

15.45 GMT: GMT Sports Direct News reports a new twist in the Etienne Capoue to Napoli story by claiming that Tottenham are lining up a swoop for Goran Pandev.

15.10 GMT: Reports in Italy say new Milan coach Clarence Seedorf is hoping to make Netherlands international midfielder Adam Maher his first signing. However, the deal may be complicated by the fact that the 20-year-old joined PSV from AZ on a five-year contract only six months ago.

There’s other positions I’d like to strengthen and we’re trying to bring in a couple," he said. “No [to Defour], there’s nothing in that. [Kiyotake] was a lad I tried to get in the summer, but things have moved on from that. He's a good player, but Nuremberg are fighting to stay in the Bundesliga.”

10.45 GMT: In an interview with Gulf News, Real Madrid's Carlo Ancelotti has said he was perhaps too rash in allowing Mesut Ozil to leave for Arsenal.

09.30 GMT: Straight from the horse's mouth, this one, and via Arsenal's Twitter account. No new deals are close in that corner of north London:
09.25 GMT: Jonas Gutierrez, who has joined the increasingly grim struggle that is Norwich's season on loan until May, has said he still does not fully understand why he fell out of the first-team picture at Newcastle. He said: "The manager told me in December I was not going to play any more, and told me to find myself another club. I don't know why that happened, and I don't understand what I did wrong."
09.10 GMT: The much-travelled El-Hadji Diouf could be off wandering again, with Leeds manager Brian McDermott saying he can leave Elland Road.

08.09 GMT: Stoke boss Mark Hughes has dismissed rumours linking Charlie Adam with a move to Galatasaray. Sky Sports quote him as saying: "I don't know where that came from.

GMT 03.40: DONE DEAL! SBS is reporting that Sydney FC has completed the signing of Serbian midfielder Milos Dimitrijevic until the end of the season.
Chelsea’s transfer activity has only just begun for the winter but the Daily Star is reporting that the Stamford Bridge club are already thinking ahead, with La Liga’s top scorer -- Atletico Madrid striker Diego Costa -- earmarked as their number one summer target. Chelsea are already the big spenders of the January window after clinching a 21 million pound deal to re-sign Serbia international Nemanja Matic, but are looking to send their summer budget into the stratosphere with the purchase of the 25-year-old Costa. The Brazilian-born striker has a 32 million pound buy-out in his contract and is wanted by Blues boss Jose Mourinho to kick-start his misfiring forward line. However, Premier League rivals Arsenal are also chasing the striker’s signature.
Across London, and a former Chelsea player could be returning to the Premier League with the Mirror reporting that Tottenham are closing in on Lille attacker Salomon Kalou. The 28-year-old Ivory Coast international has been in good form for the Ligue side this season and is rumoured to be itching for a return to England. And an interested Tottenham look ready to buy with a 3 million pound move said to be on the table. However, high-flying Lille are reluctant to lose one of their top strikers and have already stated that don’t wish to sell.
Finally, the long, drawn out transfer saga of Blackpool winger Thomas Ince could finally be coming to an end with The Telegraph claiming that French big-spenders Monaco are favourites to sign the 21-year-old. Ince has long been on the radar of many clubs both in England and abroad, but with the youngster’s contract running out in the summer, Monaco are seizing the opportunity to sign the England Under-21 international as a free agent. That’s bad news not only for Blackpool, who will receive no transfer for the player they have nurtured, but also Liverpool, which would have received a 35 percent share of the sale as part of the deal that took Ince from Merseyside to the Tangerines.
