Brendan Rodgers guided Swansea to the Barclays Premier League after a thriller at Wembley - and immediately set about the task of keeping them there.
The Swans boss has already drawn up a list of targets for chairman Huw Jenkins, who can now dip into the estimated £90million earned by Monday's dramatic 4-2 play-off final win over Reading.
"It will be very tough next year but we have targets to help us keep our identity," said Rodgers.
"It can be a big mistake to get promotion and try to do it with the same players, it's a different stratosphere with regard to pace and power. I want to give the players here a chance but we'll need to strengthen and I'll talk to the chairman. I won't break the team up but I want to add to it.
"We want to fight to keep everybody here and then bring players in to strengthen it. My fear was, if we didn't win this game, there would be players tempted to go to other Premier League clubs.
"I'd like to think now, having got there, we can reward our players for being at a Premier League club. And because they love the team it will be great for them to play for us in the Premier League."
Chelsea reject Scott Sinclair was the Swans hero with a hat-trick, including two penalties, as they reached the top flight for the first time since the John Toshack days of the early 1980s.
Stephen Dobbie was also on target, and City had to ward off a second-half fightback when a Joe Allen own-goal and Matt Mills' header brought Reading back to 3-2 before Sinclair sealed it.
"The Premier League will be a better place with Swansea in it," added Rodgers, who was sacked by the Royals just 16 months ago.
"Swansea is a beautiful place and this is all part of a great journey the club is on. I'm very honoured to lead Swansea in the Premier League and I'm really looking forward to the challenge. We were tipped to be in the bottom three this season so we'll definitely be underdogs in nearly every game next season."
