Malky Mackay admits he wants to add six new players to his Cardiff City squad before the transfer window closes.
And the Bluebirds boss hopes trialist Rudy Gestede will be a seventh signing this summer after the Frenchman scored in their pre-season win over Charlton.
"We've already signed six players and I'd love to get another six in but I'm not sure about that," said Mackay.
"We lost 12 players after last season so there was a huge hole to fill and the squad needs a little more depth."
Cardiff chief executive Gethin Jenkins promised Mackay he would have transfer funds this summer when the Scotsman was unveiled as Dave Jones' successor in June.
But Mackay has only spent money on one of his six signings so far when he lured Republic of Ireland Under-21 striker Joe Mason to the Cardiff City Stadium from Plymouth Argyle.
Former France Under-19 striker Gestede is also available on a free after his contract at Metz expired.
Gestede's winner was enough to beat Charlton Athletic 1-0 on Friday during a pre-season training camp in Spain and the 22-year-old could earn a full-time contract at the Welsh club.
"He has gone back to France but we are certainly talking to his representatives and we'll try to get something done," said Mackay.
"The guys that have come in for free are top international footballers and experienced players which is good business for this club.
"There are funds available if we try to get someone but there is a limit."
Cardiff have been linked with Scotland striker Kenny Miller and the Championship club are still hopeful that Wales striker Craig Bellamy, who enjoyed a season-long loan spell at his home-town club last season, will return to bolster their attack.
"We haven't a set number of players we want to bring in," Mackay continued.
"We will see where we are in terms of the quality of player available but we will certainly be trying to add to the squad.
"We need strength in all positions as if we look beyond our initial substitutes bench, there are a lot of kids that are in their first year in this league - and that will eventually catch up with you.
"Ideally it would be great that all of our new signings will be here for the start of the season but I don't think that will be the case.
"The transfer window doesn't close until the end of August then the loan window opens again and that's when the Premier League clubs will decide which players to let players out."
Cardiff City, who have suffered successive failed play-off campaigns, start their season at West Ham United on Sunday, 7 August.
