Manager Malky Mackay admits he will need to add to Cardiff's squad following their play-off disappointment.
lost 5-0 over two legs against West Ham
in the Championship play-off semi-final.
It was the third successive year they had suffered play-off heartache and now Mackay plans to add to his squad.
"We're certainly going to try and improve the football club again," he said.
"There's great strides been made this year on and off the pitch and I'm certainly going to be trying to push this again to make sure we get even better.
"A lot of people rely on me to lead this football team and this football club, that being the case that work has started already.
"We'll be trying to plan out the coming months ahead.
"You look at West Ham, and despite obviously the financial differences, there's a strength in depth they've got that has been apparent we don't have."
Mackay was appointed Cardiff manager last June and inherited a squad which had lost 12 players following last season's play-off disappointment.
But despite last summer's upheavals, the Scotsman says his side have taken great strides during a season which saw them not only reach the play-offs but also the
Carling Cup final
"We were lucky to manage to get a team out on the pitch the first day of the season," admitted Mackay.
"We got to a memorable cup final that will probably live in people's memories for a long time and managed to get into the play-offs with the three teams that came down with the parachute payments.
"We've managed to go in an mix in with them and it's something I'm very proud of my group of players here."
Cardiff's season ended at a ground where they had won 1-0 on the opening day of the Championship campaign last August.
The Bluebirds were already facing a difficult task after
losing 2-0 in the first leg
and goals from Kevin Nolan, Ricardo Vaz Te and Nicky Maynard secured West Ham's place in the final.
But the second leg could have been different had referee Mike Dean not waved away an early penalty claim when Winston Reid sent Kenny Miller tumbling to the floor.
"I've not seen it again, but little things change games," said Mackay.
"But West Ham were clinical today. We're obviously disappointed, but we knew it would be a tough task.
"Congratulations to West Ham, they deservedly got to the final and good luck to them."
