Deadline day will never not remind me of the 2011 January transfer window when all hell broke loose with Andy Carroll.
Things had been rumbling for some time with Carroll and there had been suggestions that United might be prepared to sell if the price was right.
In the build-up to the window, I'd been told numerous times that Carroll - despite interest from Liverpool - would NOT be sold.

Indeed, Alan Pardew had erupted at a press conference and shouted: "How many times do I have to say this - he's not for sale."
The same message was issued by the club on deadline day morning itself and Carroll, as expected, arrived and trained with the Magpies.
Carroll knocked on Pardew's door and asked about a new deal after making a flying start to life back in the Premier League with 11 goals to his name and an England call-up.
The Geordie was entitled to ask for improved terms.
There's no doubt Carroll's agent at the time, Mark Curtis, will have been looking at options for his client.
Yet no sooner had Alan Pardew's door closed, with Carroll having been told he would not be getting an improved deal, then a £30million offer was slapped on the table by the Reds.
By mid-afternoon, this had been rejected and by the time Liverpool came back with a £35million offer, Mike Ashley's private helicopter had appeared on the lush green surfaces of Benton.
Carroll later told me : "The owner then made it clear to me that I was not wanted at the club. Saying that his own helicopter is waiting for me to go down to talk to them."
And so within hours, Carroll was a Liverpool player, on a day that started with the club issuing a firm "not for sale" message.
That taught me an awful lot about the industry at that time and why things are never as they seem.
Agents will always push, a player is never "not for sale" and a footballer is never guaranteed to stay loyal to one club.
From a journalist's point of view the Carroll Deadline Day couldn't have been better in terms of drama with Carroll even giving me the exclusive inside story for ChronicleLive the next day - much to the fury of the club and Pardew who tried to counter the interview with his own version of events.
But Carroll's words were too strong, he'd effectively been pushed and while it made him a fortune, there was an argument that he would have signed a new deal had it been presented to him that day.
Incredibly, the drama didn't end there.
Newcastle tried to sign South American star Diego Forlan in the aftermath of Mike Ashley's helicopter taking off.
The fee was £14million from Atletico Madrid but the deal broke down when Forlan started to demand what was described to me as "astronomical" wages.
In the end, United ended up with Finland international veteran Shefki Kuqi.
Kuqi couldn't believe his luck and while he didn't score during his time on Tyneside, he savoured every moment.
Fast forward to August 2019, I received a phonecall very early that Carroll was on his way back to Newcastle on deadline day after being released by West Ham.
This was a day that needed genuine focus in order to follow the story properly.
Those close to Carroll were dropping hints as to where he might be and what time he'd be arriving in NE1.
Some journalists were sold a dummy by the rumour he'd arrive next to the Sir Bobby Robson statue. I was told it might be different.
Myself and a photographer situated ourselves at the Leazes End of St. James' Park and Carroll arrived in a friend's car.
To photographer Simon Greener's credit he only had a second to get the snap of Carroll getting out of the car as a huge roller shutter came down - but he managed it in some style.
The story was in the bag, Carroll was coming home and the next day it was front page stuff.
