A look at Radamel Falcao's goalscoring record makes interesting reading for Manchester United fans - his most prolific season came in 2012-2013 when he bagged 34 goals in 41 games in all competitions as Atletico Madrid won the Copa del Rey and finished third in La Liga. Despite an injury hit first season for Monaco he still managed to score 11 goals in 19 appearances in all competitions giving him a return of 0.58 goals per game.

John: This is only the third transfer window since Sir Alex Ferguson retired, and since then Manchester United have spent the same amount in 18 months that Fergie spent on players in 12-15 years! This whole situation just proves how great a manager SAF really was that he was able to get the best out of some average players.

BBC Sport's Simon Stone, who is reporting that a loan fee of around £6m has been agreed for Radamel Falcao to join Manchester United: "Think it is now certain Danny Welbeck will leave, either on loan or sold. There had been a desire for him not to join a top-six rival but the club now accepts stopping him going would be pointless under the circumstances. That brings Arsenal, Everton and Tottenham into the equation."

Cardiff City

Wales defender Danny Gabbidon is closing in on a return to Cardiff City as a player-coach.

Gabbidon, who is a free agent since his contract at Crystal Palace expired, has been training with the Bluebirds during the summer.

The 35-year-old was a huge fans' favourite during his first spell at Cardiff, making more than 200 appearances between 2000 and 2005.

Gabbidon has won 49 caps for Wales, and is eager to prolong his playing career to stay in manager Chris Coleman's plans.

As the former West Ham and Queens Park Rangers centre-back is a free agent, the deal could be concluded after the transfer window shuts.

Finally we have a 'done deal'. And it's courtesy of Karim El Ahmadi, who has agreed a three-year deal to return to Feyenoord with immediate effect after two years with Aston Villa.

Ali:, external Even Fergie couldn't attract the likes of di Maria and Falcao. In LVG we trust.

Jonathan Sheppard:, external You know LVG said MUFC was unbalanced…. why not add another attacker.. just what's required.

Philip Townley:, external LVG needs to sign a defender! On a positive note it looks like Welbeck is not needed anymore. He was terrible anyway!

We're 10 hours and 40 minutes into transfer deadline day and, as yet, we have not had a single confirmed transfer. All this talk of Manchester United signing one of the best strikers in the world is keeping things interesting, though. Will Manchester City, Arsenal, Chelsea or Liverpool respond with a surprise big deal of their own?

BBC Sport's Simon Stone on Radamel Falcao, who is close to a loan move to Old Trafford: "Manchester City opted against pursuing a deal as they could not make space in their squad for the Colombian.

"However, after a shocking start to the season that has seen them collect two points from three games, and score only twice, and get beaten 4-0 in the Capital One Cup by League One MK Dons, Louis van Gaal has decided to reinforce his squad. Like most of Europe's top clubs, United had been made aware of Falcao's availability over the past 48 hours."

Mr. Palindrome:, external Whatever you guys say, at least LVG is spending the money. Moyes just tried and failed and in the end bought Fellaini.

akachukwu daniel:, external Please who will pass the ball to Falcao, Cleverley??

Adam Green:, external Ridiculous signing by United even if a loan. Pointless having a world class striker if your best defender is Chris Smalling.

Fiorentina on Twitter:, external 26-year-old MCFC right-back Micah Richards has landed in Florence ahead of a potential move...

Jake Saunders:, external Manchester United have no more excuses now, they have to perform. Can't believe they've managed to get Falcao!

Tom Quante:, external Falcao to Man United is a massive swoop for LVG, very jealous.

Vince:, external With Falcao now coming to the Premier league and United it seems anything is possible in this transfer window.

Man Utd

BBC Sport's Simon Stone on Radamel Falcao, who is close to a loan move to Old Trafford: "Manchester United have blown deadline day 2014 apart with this deal.

Long term it raises huge questions over the make up of Louis van Gaal's starting line-up. It is impossible to get Falcao, Robin van Persie, Juan Mata, Wayne Rooney and Angel Di Maria into it surely?

"Short term... where will Danny Welbeck end the day? He must know there is no place for him at Old Trafford."

Lloydy: Hearing QPR are looking to bring in Jermain Defoe, Scott Parker and Mo Diame today.

Ricky in South west: My source at Arsenal has informed me that they could be making a deadline day move to bring Thierry Henry back to the club to solve their striker situation.

BBC World Service reporter John Bennett: "It looks as though AC Milan are going to do some business today."

"Gazzetta Dello Sport are reporting that French winger Jonathan Biabiany will join the club from Parma.

"Biabiany used to play for Sampdoria and Inter and scored six goals in 36 Serie A games last season.

"Milan Centre-back Cristian Zaccardo could be going back to Parma as part of the deal."

Carlisle United have sacked manager Graham Kavanagh following Saturday's 5-0 defeat by Cambridge. A club statement said "club captain Paul Thirlwell and goalkeeping coach Tony Caig have agreed to take the training sessions and handle team selection matters in the coming days."

Harry Page:, external It's Christmas!!!

Morenikeji Dawodu:, external BOOM #Falcao

Ryan Kerr:, external With all the money spent by Man U, I can no longer say that City and Chelsea bought the title. Now we wish we could buy it.

BBC Radio Leeds's Adam Pope: "After the weekend signings of loanees Adryan and Dario Del Fabro, Leeds are expected to add a 15th summer addition in Paraguayan striker Bryan Moreno from Nacional. Talks have been ongoing since last week."

Phil McNulty
BBC Sport chief football writer

"Liverpool manager Brendan Rodgers hinted at one more incoming deal after the win at Spurs - but the feeling at Anfield now is that it is more likely to be outgoing deals, with the likes of Lucas potential departures."

BBC Sport's Simon Stone: "A loan deal is agreed for Radamel Falcao to join Manchester United, subject to a medical and personal terms being agreed."
