For football fans, today has all the tension of a cup final penalty shoot-out without a single ball being kicked.

Clubs in England and Wales have until 11pm to add to their squads. While in Scotland the deadline is midnight.

For football agent George Swan it's his busiest day of the year and, at 22, he's the youngest agent in the country.

"Even toilet breaks, we try and stay away from them because you don't want to miss a massive call," he tells Newsbeat.

His clients include include Aston Villa's Robert Snodgrass, West Brom's James Morrison and Middlesbrough's Stewart Downing.

Arsenal, Manchester City, Chelsea and Tottenham are expected to be among the big spenders today.

Deals are sometimes completed seconds before the transfer window closes leaving fans to spend the rest of the day speculating about new signings.

"So this morning, it was a case of waking up reading the tabloids and looking at the news on the telly seeing what's gone on overnight," George said.

"Then the agents I work with, we sit down and look at which of our players could be moving and assess the situation."

The 22-year-old is a former professional footballer who joined Manchester City's under-14 squad in 2009 for £450,000.

He went on to play for clubs including Sheffield Wednesday, York City and Wolverhampton Wanderers before injuries forced him to retire in 2014.

George says he won't be away from his phone or leave the office well after tonight's transfer window has closed.

"You can't afford to miss a call. Then you miss the chance of one of our lads moving to another club and someone else's player getting that call.

"As long as the player signs the contact the rest can be sorted after it all," he added.

George Swan thinks this year's summer transfer window could be as busy as it was in 2011 when UK clubs spent hundreds of millions on new players.

"Arsenal are maybe the big talking point, are they going to lose Alexis Sanchez? Who will they replace him with.

"When I was younger I used to love transfer day. Even as a player you sit and text other players and talk about what's going on."
