The reasons for unsuccessful transfers often lie close to home, whether players care to say so or not.
Federico Bessone left Leeds United last week knowing that the impasse he encountered at Elland Road was of his own making, a problem for which he was largely to blame.
It would be reasonable to expect a flood of bitter reflection from a player who joined his chosen club in July and walked out again – albeit on loan – the following January but Bessone's attitude is painfully honest. "I feel disappointment, yes, but only with myself," he said.
"Not with anybody else. The manager gave me a chance and I didn't play to my best. You know when you're at a big club that if you don't play to your best, other people are waiting. I lost my place."
That, concisely, is Bessone's Leeds United career in full: eight consecutive starts before the end of September and many more weeks spent in the wilderness.
The Argentinian left-back carried an injury for two months but he realised that his performances had already been opened to close scrutiny.
When Leeds confirmed to him midway through January that George McCartney would be returning to Elland Road on loan until the end of the season, he resigned himself to seeking the same offer elsewhere.
Leeds initially signed McCartney on September 24, a week and three days after Bessone limped out of a 5-2 thrashing at Barnsley. To date, it is his last appearance for the club. "George came in and did well, and anyone who does well has to be playing," Bessone said.
"You know that and I know that. I never argued with his place in the team but I couldn't be happy about my own situation.
"Life as a footballer is like this – when you're playing, everything is good.
"When you're not playing, everything is wrong. You're mentality changes and you don't feel so good about yourself.
"The only thing I want from my career is to play football and to enjoy playing football.
"I had some very good meetings with the manager (Simon Grayson) and he was very honest.
"When he told me that they'd be signing George McCartney for the rest of the season, I said then that I had to go. I don't think it's right for a footballer to say 'okay' when they're not going to play any games."
Charlton Athletic took Bessone on a half-season loan on the last day of the January transfer window.
The following evening, Bessone was named in Charlton's starting line-up for a 1-0 win over Colchester United at The Valley. Overnight, he moved from a peripheral position at Leeds to the front line of a club who are close enough to the top of League One to win it this season.
It is still a frustration for Bessone that his summer transfer came to
The 27-year-old turned down a new contract at Swansea City and ignored offers from other clubs to accept a three-year deal with Leeds in July.
"They were my first option, my first choice," he said. "I was so pleased to go to Leeds and to begin with I was playing every week. I didn't play as well as I can and I picked up an injury but I did hope I'd get a second chance.
"The way Leeds play is different to how Swansea play – a different type of football – and it took me some time to understand that.
"I've watched games from the stands for two or three months and I think I know now how the team play and what I need to do to be part of that.
"If I got a second chance then maybe I'd be better.
"But Charlton are a good club and the plan here is to get the club into the Championship.
"If they weren't a good club then I wouldn't be here because I wanted to be with a team who have ambition and something to play for.
"At the moment, I'm only thinking about Charlton. I'll do everything I can for them until the end of the season and then see what happens.
"I'm happier now than I was two weeks ago. On Monday I joined Charlton and on Tuesday I was in the team. That was after three-and-a- half months of not playing football.
"I'm a footballer and footballers like to play."
Bessone's loan to Charlton was agreed with a possible view to a permanent deal.
That option is likely to depend on several factors, not least Bessone's form in the interim and Charlton's league status when the season ends.
The defender will have two years left on his contract at Leeds in June and has not abandoned the idea of returning to Elland Road and thriving at the second attempt, unlikely though that scenario seems.
McCartney talked last week of his interest in joining Leeds from Sunderland permanently and Grayson also has Ben Parker available.
Parker's appearances against Cardiff City and Arsenal in the second week of January were nothing less than confirmation of Bessone's position in the selection order.
McCartney's return left it beyond doubt.
"Players have gone out of Leeds before and then had a chance with the first team (at Elland Road)," Bessone said. "Davide Somma did it last season and he's back performing at a good level. If I play well with Charlton then you never know. The manager might feel I'm worth a second chance.
"I've got two years on my contract after this season so I'm not saying that
"I don't have a future there. I don't know what will happen.
"But I can't feel angry because I don't blame anyone. I'm only disappointed in me."
