Killie are still posting Scrabble things.

New Celtic signing Adam Idah: “It’s such a huge club with such a big history behind it and I can’t even put into words what it’s like to be at Celtic.

“My family and my friends are all delighted that I’m here and I just can’t wait to get started. All of us back home support Celtic so it’s huge for me and I’m so excited to be here.

"I want to play games, I want to help this team and the aim for me is to win those two trophies and I want to score a lot of goals for this club."

Finally, it's confirmed.

Celtic have signed Norwich striker Adam Idah on loan until the end of the season.

The 22-year-old, who has 22 caps for the Republic of Ireland, becomes Brendan Rodgers' second signing of the window.

He's scored 17 goals in 115 appearances for Norwich, with seven coming this season.

We've got news from Celtic Park...

A complete coincide that the guy in the Killie top thought about picking up the ST in his game of scrabble...

Definitely nothing to do with Kevin van Veen's reported links with a move to Paisley earlier in the day.

Oh, and we're waiting for David Turnbull's move from Celtic to Cardiff to get the green light.

Kinda expected that to be announced by now...

Rangers have concluded their business with the loan signing of Lens winger Oscar Cortes.

Kilmarnock beat Motherwell and St Mirren to the signing of Kevin van Veen, also on loan.

Ross County added defender Michee Efete, while Livingston signed David Carson from Inverness.

St Johnstone secured Adama Sidibeh from Warrington Rylands and Motherwell have sealed a loan for Rangers' Adam Devine.

Hibs confirmed loans for defensive duo Owen Bevan and Nectarios Triantis, while Celtic's Mikey Johnston has joined West Brom for the rest of the season.

So where are we likely to see more business?

Celtic are still yet to confirm Adam Idah, will they look to add any more?

Motherwell must still be on the search for a new striker after failing to land Kevin van Veen, does the same apply to St Mirren?

And we understand Hibs are looking to add another body.

There it is, now confirmation from Kilmarnock's side that Kevin van Veen has signed.

There are no quotes from the Dutchman on the Ayrshire club's statement.

Killie just seem to be posting videos of a guy playing Scrabble.

It is pretty quiet down Pittodrie way, as things stand it is not looking like there will be any comings or goings.

I guess the good news for the Dons fans is that Duk will be sticking around.

There had been interest in him during the day but nothing that came anywhere near the club's valuation.

The hope now must be that the new manager coming in can perhaps act as a catalyst for getting the best out of him again in the second half of the season.

Kilmarnock are about to announce something.

No prizes for guessing what it might be...

So Hibs fans out there.

With just over an hour left in this window and one space left to fill, would you sign a defender, a midfielder or an attacker?

Getting Kevin van Veen on board is absolutely massive for Kilmarnock.

A brilliant piece of business by Derek McInnes and the club. So prolific, so cultured and just looks like a good guy to have around the place.

Hugely exciting for the fans. Deal of the window in Scotland.

If that's the end of your window, Gers fans, how do you rate that window?

Let us know using they thumbs...

The completion of the Oscar Cortes deal means that is business complete for Rangers in terms of new signings.

The Colombian winger joins Fabio Silva and Mohamed Diomande as the January arrivals at Ibrox.

From the green end of Glasgow to the blue side, Jonathan has an update from Ibrox...

Gary: If we don’t sign players who are going to strengthen the starting team then there is no point in signing anyone. Our squad is too big already and we don’t need any more squad players.

Hugh: I think we will look back on this window as a wasted opportunity. We have failed to strengthen the squad in any position and we have also failed to clear out any deadwood. A few injuries and we will be struggling. The board have shown a lack of ambition and have taken the support for granted.

Tom: We need a striker with Oh the only back-up we have for Kyogo, and we definitely need a full-back. Greg Taylor needs competition and Bernabei just doesn’t seem up to scratch.

Danny: I feel in years gone by, Celtic were prone to making an impact signing in the January window. The likes of Roy Keane - players nearing the end of their careers but still good enough to pull on the jersey and get fans excited. But nowadays we get mediocre players who we’ve never heard of. Players like Dele Alli and Coutinho are in limbo… Why not?

Jim: Not the cleverest scouting; maybe Celtic don't have the pulling power of old? Surely any targets should have been sounded out a lot earlier. Poorly organised.

Dan: Still badly need a left-back. We have been rumoured to be after Kurzawa from PSG, so hopefully that goes through even just on loan. I don't see much else coming in. Lagerbielke might end up staying after all; Holm and Yang could do with being loaned out.

Celtic fans, I don't think I even need to ask the question.

I assume almost all of you are disappointed with your club's window so far.

Let's see what some of you have been saying...

County fans, you will surely be delighted to know Yan Dhanda is staying for the rest of the season.

Yes, he goes to Hearts at the end of the campaign, but not losing him this month is huge.
