According to Alan Nixon via Patreon, the Seasiders spoke to several options last week, but Rosenior has emerged top of the pile.
Michael Duff was overlooked for the position, Nixon reports, and former Lincoln boss Michael Appleton is also said to have been interviewed for the role.
Rosenior is now reportedly set for a meeting with Derby County boss Wayne Rooney to confirm his departure from the club.
Rosenior became assistant boss under Wayne Rooney at Derby following Philip Cocu’s departure from Pride Park in November 2020.
Helping steer the Rams clear of Championship relegation in 2020/21, the 37-year-old once again contributed to another brave, but ultimately unsuccessful, survival effort at the club in 2021/22.
It remains to be seen who Rooney chooses to succeed Rosenior as Rams’ assistant boss should reports of his departure come to fruition.

This is a really interesting appointment from Blackpool.
Although it is Rosenior’s first managerial role, he has gained invaluable experience working under Wayne Rooney at Derby County in testing circumstances, and it will be exciting to see how the 37-year-old gets on.
The Seasiders had plenty of success under their former boss Neil Critchley, who was also a young coach, and if Rosenior can continue to establish the club in the second-tier, he will be a hit at Bloomfield Road.
The consequences this move has on Wayne Rooney and Derby County remain to be seen, however, at this moment in time, the Rams have more pressing issues to deal with.
