Rob Millward: For anyone who works for a football club spare a thought for Arsenal's shirt printers with Aubameyang, Mkhitaryan and Lacazette starting as a front three.
'Mkhi' looks a lot happier than 'Auba' at this reunion?
How excited are Arsenal fans to see these two on the pitch at the Emirates together?

I’ve just been speaking to journalists in Spain, Italy, Germany and France for our “Sport Today” radio programme on the BBC World Service and the one word that kept coming up was “quiet.”
Here in England we seem to be monopolising all the fun when it comes to deadline day.
Our French correspondent was expecting a couple of last-minute deals but the other three have already got their feet up.
One move happening in Italy though; Sporting left-back Jonathan Silva will be Emerson Palmieri’s replacement at Roma. Italian media have pictured him having a medical in Rome.
Championship strugglers Bolton have signed Tyler Walker - son of Des - on loan from Nottingham Forest. Does that pave the way for Gary Madine to now leave the Trotters?I've seen some telephone numbers banded around when it comes to a potential fee for Madine...
The Premier League paid £174m to agents in 2016-17, up from £130m, with Manchester City being the biggest spenders (£26.3m) ahead of Chelsea (£25.1m) and Manchester United (£19m).
So what better business to get into? Or to push your kids into?!
Bring home the bacon and take this CBBC quiz now...
I'm not very good it turns out...
Burnley
Burnley midfielder Steven Defour has been ruled out for at least another two months after the news that he needs surgery on his knee.
A blow - get on the phone Sean Dyche!
There's four hours of the window left, most Premier League teams are about to play a game, can they still find time to sneak one through?
Here's news from one club which may mean they need to...

Some movement at both Newcastle and Sunderland to let you know about.
Newcastle winger Rolando Aarons has gone on a cultural exchange trip to Hellas Verona, while Sunderland have signed Ovie Ejaria on loan from Liverpool.
Thanks Caz, go safe in the Korean snow!
Fancy a little transfer update? They're still flying in...
Right, on that bombshell I'm off to the Winter Olympics.
I'm going to leave you in very capable hands for the remainder of transfer deadline day.
Welcome, Tom Rostance.
YAAAAAAAAAAAAASSSSSSSSSSS.
Bang on.
Four hours to go until the window shuts!
For the first time since I took over this live text at 15:00 GMT, I'm going to get my hourly countdown bang on.
So without further ado...

Just spoke to Sam Allardyce in the tunnel at Goodison. He says five of his players have been approached by other clubs today, but none of them are going anywhere.
Like Geoffs/Jeffs, you also don't get a lot of people called Pontus.
But Watford have found one!
Goalkeeper Pontus Dahlberg has signed on a five-and-a-half-year deal. The 19-year-old will return to IFK Göteborg on loan for the rest of this season.
Anyone fancy a maverick midfielder? Potential matchwinner, potential liability?

Another through the Emirates exit door.
Arsenal full-back Mathieu Debuchy, who had been on loan at Bordeaux this season, has joined Saint-Etienne on a six-month deal, after having his contract terminated with the Gunners.

Understand Alexsandr Mitrovic's loan deal from Newcastle United to Anderlecht has broken down.
I was only saying earlier in the office that you don't get many Jeffs/Geoffs these days.
As if by magic, one appears on transfer deadline day. Or disappears, actually.
Arsenal have sent Jeff Reine-Adelaide on loan to French club Angers for the rest of the season.
The France youth international has spent most of his season with the Gunners' U23 squad.
Also, in non-Jeff news, Chuba Akpom has joined Sint-Truidense in the Belgian top flight on loan for the rest of the season.
