Here's all you need to know about the January transfer window...
When does the transfer window close?
The 2017 winter transfer window, which opened on January 1, will close on Tuesday, January 31 at 11pm.
However, clubs can complete transfers after 11pm if they have submitted a 'deal sheet', asking for more time to file the complete paperwork. This can extend their deadline until 1am in some circumstances.
Do European leagues have different dates?
According to FIFA, the German and French transfer windows open and shut at the same time as in England, but Spain's opened on January 2, while Italy opened for business on January 3. Both Spain and Italy also shut on the 31st.
Will players signed on the Monday before deadline day be available for the midweek fixtures?
There are 14 Premier League teams in action on deadline day, with the remaining six playing the next day. To be eligible for those deadline day games, players will have to be registered to their new teams before midday Monday. Likewise, players signed on deadline day must be signed by midday if clubs want to use them on the Wednesday.
Will it be a record-breaking window for transfer spending?
Premier League clubs spent £1.194bn during the summer transfer window, and there should be plenty more cash being splashed during January as teams fight for titles, Europe and to stay up.
There was £172.65m spent in last year's winter window, although the two biggest spenders in Newcastle (£29m) and Norwich (£22.29m) were both relegated at the end of the season.
How will Chinese clubs affect transfers in Europe?
Oscar's big-money move from Chelsea to Shanghai SIPG has highlighted the potential for more star names being snapped up by rich clubs in the Chinese Super League.
Unlike in the major European leagues, the transfer window doesn't close for Chinese Super League clubs until February 28 - but Premier League players cannot move once their domestic window closes on January 31.
