Paul Ince feels he could need as many as eight new signings if Blackpool are to be competitive in the Championship.
The Seasiders find themselves short on numbers and need to work quickly if they are to bring bodies on board and integrate them into their squad before the 2013/14 campaign gets under way.
Ince is doing his best to make the required additions, with a number of players offered trial spells.
He hopes some of those will do enough to earn a permanent stay, with the size of the task facing him in his first full season in charge at Bloomfield Road beginning to dawn on him.
Ince said in the Blackpool Gazette: "There's a lot of work to be done. We need to get a core of the team. We probably need seven or eight more players in yet.
"The season is getting closer, so we are playing catch-up."
One of those to have been offered an opportunity to impress is Swedish striker Osman Sow, with the 23-year-old having figured in Saturday's friendly victory over Penrith before flying home to link up with his current employers Syrianska FC.
Ince said: "The boy Osman did well but it's always difficult to play in those games.
"He played for his current club the following day, so he must be shattered."
