And Sullivan has assured Allardyce that funds will be made available as the club look to cement their place in the English top flight.
“Our planning has already started to make sure next season is even better than this one,” Sullivan is quoted as saying by talkSPORT.
“A crucial factor of that will be recruiting the right players in the right positions.
“Our aim for the coming season is to bring in four or five players that will strengthen the squad and provide Sam Allardyce with greater options and variety next season.
“We will be aiming to bring in at least one proven goal-scorer to further bolster our attacking threat.”
