Hartlepool United boss Colin Cooper says the deal which took striker Luke James to Peterborough 'had to be right' for the club.
The 19-year-old had been linked with Peterborough for several weeks and even submitted a formal transfer request in an attempt to force the move through.
But the clubs had failed to agree a deal until Peterborough made an improved offer on transfer deadline day which Hartlepool accepted.

Hartlepool United have confirmed that striker Luke James has handed in a written transfer request.
A club statement read:
Pools striker Luke James has today handed in a written transfer request.
The club has acknowledged the request but advised Luke that he remains under contract to Hartlepool United.
There will be no further comment at this time.
The 19-year-old has risen through the youth ranks at Victoria Park and was voted the club's Player of the Year and the Players' Player of the Year last season.
Colin Cooper has made his second signing of the summer for Hartlepool United - the former Middlesbrough man Stuart Parnaby.
The club said Cooper was quick to make his move once he realised Parnaby was a free agent, because he can play anywhere across the back four or in midfield.
Parnaby grew up in County Durham and rose through the youth ranks at Middlesbrough. He was part of the Birmingham City side that beat Arsenal to life the League Cup in 2011.
Hartlepool United could be without winger Andy Monkhouse for up to six weeks due to a hamstring injury.
The 33-year-old picked up the problem during the club's 4-0 League Two win over Bristol Rovers on Saturday. Scans have revealed Monkhouse has a grade two strain in his left hamstring, which normally requires four to six weeks in the treatment room.
Manager Colin Cooper said: "It's disappointing news because Andy has played a lot of games for us this season in a few different positions as well.
He added: "It presents an opportunity for someone, if not Jack [Compton] then one of the other players who think they can have an impact in that position."
Monkhouse has scored five goals in 34 league appearances for Hartlepool this season.
Middlesbrough football club has appointed Craig Hignett as assistant head coach to Aitor Karanka.
Hignett has left his position at Hartlepool United, where he has been doing the same job for Colin Cooper.
He returns to Middlesbrough, a team he once played for, just ten months after he left his post as a youth coach at the club. During his career, he made 194 appearances for Boro - scoring 48 goals.
Hartlepool United boss Colin Cooper is hoping to keep the pressure on the teams above his side in League Two with a victory over Southend tonight.
Hartlepool have bolstered their squad with the loan signings of Jack Barmby and Luke Williams.
Midfielder Barmby, who is the offspring of the former England forward Nick, arrives from Manchester United, whereas Williams has made the shorter move from Middlesbrough.
