Cobblers have already begun work on signing a replacement for Liam Roberts following confirmation of the goalkeeper’s move to Middlesbrough.
Roberts was outstanding for Town last season but always looked unlikely to extend his stay at the club following the expiry of his contract, especially with big clubs from the Championship showing an interest in his services.
Confirmation of his move to Chris Wilder’s Boro was announced on Tuesday afternoon but it came as no surprise to Brady, who has wished Roberts well and is now focused on finding a replacement.
"Liam was good for us and we were good for Liam," said the Town boss.
"We identified Liam when he was available last summer as part of our thorough recruitment process and not only did he do very well for us, we worked with Liam to not just help and improve his overall game but to get his career moving in an upward direction again.
"We were keen to try and keep hold of Liam and we made several good contract offers but in the end the chance to move to the Championship and a club like Middlesbrough was an excellent opportunity for him and I think everyone understands that.
"We thank Liam for his efforts and wish him well for the future. This was not unexpected and we are progressing our work to recruit a goalkeeper."
Roberts has put pen to paper on a two-year deal with Boro.
