That’s an hour later than England, who have to wrap up business by 11pm - but who’s going where?
Celtic look like being the most active Scottish side, with the Hoops hoping to bring in Scotland midfielder Barry Bannan from Crystal Palace on a loan deal, while PSV Eindhoven youngster Zakaria Bakkali is also on Ronny Deila’s radar.
A deal was agreed with Derry City for Michael Duffy at the weekend and we also expect the Hoops and Dundee United to be locked in negotiations over Stuart Armstrong and Gary Mackay-Steven while Virgil van Dijk looks unlikely to leave Glasgow in this window.
South of the Border, fans are expecting a rather genteel end to the window - Chelsea should wrap up the signing of Fiorentina winger Juan Cuadrado while Ronald Koeman has hinted at new faces coming in at Southampton, with Tonny Vilhena of Feyenoord and Benfica’s Filip Djuricic (once linked with Celtic) on the Dutchman’s radar.
The Manchester clubs are unlikely to make any final-day moves as City wrapped up the signing of Wilfried Bony earlier this month while Louis van Gaal promised a quiet January window for United - but Darren Fletcher could be on the move despite the collapse of his West Ham switch.
Elsewhere, Arsenal have already brought in Paulista from Villarreal and we fully expect Harry Redknapp to be wheeling and dealing as the clock ticks down with Spurs striker Emmanuel Adebayor reportedly high on Harry’s list.

Selhurst Park boss Alan Pardew is happy to let the Scotland midfielder leave on a temporary basis in order to get game-time, and the arrival of Jordon Mutch earlier this month has pushed Bannan down the pecking order in London.
Bannan was in the crowd to watch Celtic ease past Rangers into the Scottish League Cup final yesterday. (Daily Record)
DUNDEE UNITED have revealed they knocked back two fresh bids from Celtic for Gary Mackay-Steven and Stuart Armstrong on Sunday night.
Mackay-Steven has already agreed a pre-contract with the Hoops, who are keen to bring him in now while Ronny Deila is a big fan of Armstrong.
However, the two bids reportedly fell well short of the Tannadice club’s valuation of the two midfielders, although Celtic are expected to test United’s resolve with further bids today. (Various)
HEARTS are set to bring in Dutchman Kenny Anderson from RKC Waalwijk, as the Jambos look to replace Jason Holt.
Anderson, 22, has a Scottish dad and a Dutch-Indonesian mother, and has been omitted from the Waalwijk squad to face FC Twente II tonight in order to hold talks with Tynecastle chiefs. (STV)
IAN BLACK has hit out at Craig Thomson, accusing the whistler of bottling out of sending off Scott Brown in the dying minutes of yesterday’s Old Firm clash.
Black was on the end of a crunching challenge from the Celtic skipper, describing it as ‘naughty’ but claiming Thomson should have shown the red card to the former Hibs midfielder.
“If [the referee] was a bit of a man and it was earlier on in the game then Brown would have walked up the tunnel. But it was the end of the game and I felt he bottled it,” explained Black. (Daily Record)
RONNY DEILA bemoaned the state of the Hampden pitch after Celtic’s 2-0 win over Rangers, claiming it was ‘very hard for the players’.
The Norwegian gaffer added: “Skill needs good pitches - it’s more fun to watch. This wasn’t good enough.” (Daily Express)
