Coventry City CEO Steve Waggott has said that the club needs more season ticket sales.
The club have done very well considering how poor the team was last season, only ensuring their place in League One on the final day of the season, to sell just under 5,000 ordinary season tickets.
With the owners not funding the club anymore and encouraging it to be self sufficient, every pound the club can raise from season ticket sales is vital and Mr Waggott said to the club website: "Our sales have helped fund a positive transfer window so far but as Tony Mowbray has said recently, there is still a lot of work to be done and players to bring in.
"We'd still like to bolster our forward line and the wide areas, and season ticket sales are imperative to get these deals over the line.
"As our fans know, season tickets are the club's main source of revenue and we need to reach our target to fund a squad which will be capable of success next season under the Salary Cost Management Protocol."
