Agent Sky Andrew told The Footballers' Football Show the countdown to the transfer window deadline is a stressful time for players, agents and football clubs alike.
With the summer transfer window closing at 11pm on Friday, the past week has been a busy one for clubs across the country who are eager to add to their squads - and also for agents desperately trying to engineer a move for their players either unhappy or unwanted at their current side.
"It's a strange time," he said. "There's a lot of talk in the lead up to the transfer window and there's a lot of speculation and supposition.
"Most of it doesn't come to fruition but in the last few days people put their money where their mouth is, so to speak, the offers come in, and you see whether clubs really do want to sell certain players and whether clubs really want to put the offers in.
"Some agents find themselves in a very difficult position. In an ideal world an agent would just represent a player or club, but some agents find themselves in this abyss of being deal brokers and often they're the ones who cause the problems in the deals."
Andrew also believes the transfer window causes problems for clubs by unsettling players.
"On the one hand the transfer window creates stability, because managers know what squads they've got for a period of time between windows," he said.
"But on the other hand footballers are creatures of habit so when the transfer window is on they say 'is anything going to happen with me, he's moving, he's earning this,' and that's normal.
"But over a period of time I think everyone realises - managers and chairmen especially - the best situation is just to have stability, have your players under long contracts and not have this grey area. This speculation is great for journalists and the public but for chairmen and managers it's a nightmare."
Reading boss Brian McDermott agreed: "It is a nightmare! We tried to do all our business early - we've signed nine players this summer - because we wanted all the players at pre-season, which was the most important thing for me.
"Having said that, sometimes on the last day of the window something just pops up and we think 'we can do that deal'.
"I'm really happy with the squad I've got - we've got a stable club and that's why we've been successful - and I'm happy with how we work. But something might come up on the final day, you never know."
