Michael Laudrup has warned Swansea he will not be able to eclipse last season's achievements without major investment.
Laudrup was a resounding success in his first season at the Liberty Stadium, guiding the club to ninth in the Premier League - their highest finish since 1982 - and delivering League Cup glory that secured European football.
The Dane signed a one-year contract extension in March which ties him to the club until summer 2015 but only after being assured of money to strengthen his squad ahead of a maiden Europa League campaign.
But without significant funding, the 48-year-old reckons last term was as good as it gets.
"Unless we find a couple of hundred million pounds I think last season we achieved nearly the maximum we can in terms of the table," Laudrup said.
"There are always things you can improve but there are not many higher positions we can look at.
"Even consolidating is going to be very difficult.
"Some of the teams below us this season will invest heavily: West Ham, Newcastle, Aston Villa. They are huge clubs who want to take the place where we are right now."
Laudrup's agent, Bayram Tutumulu, has claimed the former Denmark captain snubbed several job offers to stay in South Wales but is confident a high-profile club will soon come calling.
"Michael Laudrup, just now, is very happy at Swansea City. Of course Michael has had offers from elsewhere," Tutumulu said this week.
"Other teams can wait one or two years. We know Michael is going to train the big teams but this is not the moment."
Tutumlu also claims the ex-Real Madrid and Barcelona star can attract exciting new signings such as Jose Canas, who will join on a free transfer on July 1.
Tutumlu said: "Canas from Real Betis - one Premier League team have offered him double his salary. And you know what the boy tells them? He tells them, 'No, I want to go to Swansea City'.
"Players have other teams offering them more money but they prefer to come to the team of Michael Laudrup."
