All the transfer news, rumors and signings from January deadline day

Welcome to the winter transfer deadline day, which should be quite a bit less chaotic than the one in the summer. Don't expect to hear about Andy Carroll and Fernando Torres flying around in helicopters on Monday. This is likely to be the quietest deadline day in recent memory.

All day, there will be a running timeline of the biggest rumors as they come in, as well as actual done deals. Because it's often extremely difficult to separate the fact, from rumor, from outright fiction on deadline day, we're going to make that very easy here.

This post will be updated regularly until the last deals of the transfer window are completed. The window slams shut at 6 p.m. ET, 11 p.m, local time in England. It shuts a bit earlier across most of the European continent, while Germany's window is still open until early on Tuesday.

The biggest done deals

Stoke pulled off a stunner, signing Giannelli Imbula from Porto.

Fabio Quagliarella has joined Sampdoria.

Seydou Doumbia has moved from Roma to Newcastle on loan.

Bayern Munich have added Serdar Tasci from Spartak Moscow.

Abdoulaye Doucoure has signed for Watford.

Croatian wonderkid Andrija Balic has signed for Udinese.

Real Madrid have loaned Denis Cheryshev to Valencia.

Arsenal have confirmed Mathieu Debuchy's loan to Bordeaux.

Oumar Niasse has joined Everton for £13.5 million.
