Jurgen Klopp is confident Liverpool won't need significant changes when they look to retain their record-breaking Premier League crown next season.

But the Reds boss admits uncertainty in the transfer market means some clubs will be tempted to take "risks" in an effort to close the gap on his side.

Liverpool's domestic dominance is such that last week they ended their 30-year wait for the title by becoming the first team in history to secure the title with seven games remaining.

A heavy 4-0 defeat to Manchester City on Thursday highlighted the outgoing champions will be keen to regain the crown next season while Chelsea have already spent big ahead of the transfer window opening this summer with Manchester United also likely to reinforce.

Klopp has previously indicated Liverpool are unlikely to do major business, and is adamant there doesn't have to be an overhaul of the squad's approach for the Reds to be ready next term.

"We don't have to change," he said. "We have to do the good things and then keep on improving the not so good things.

"Having better messages for the boys, that's what we have to improve 100%. We are on a pretty interesting level but it is still possible to make it better.

"I don't expect perfection from my players. I want to play next season as good as possible. If you can be very successful by losing six or seven or eight games then I will be surprised.

"When I look at the league now, I see so many teams really improving. It's a difficult time, we don't know who is going to take much risks with transfers and who doesn't do that, we will see that.

"We will make sure that we are ready for a proper competition and a proper challenge. That's what I expect, not that we become champions by winning 38 games, otherwise I'm not happy any more. These boys are exceptional characters and I don't doubt them even 1%. I trust them 100%.

"They are not perfect and make mistakes, but they always strike back. Since I have known them, they have always improved and always struck back. They are thoughful. As I've said, we won't defend the title, we will attack it. We have to be prepared for the other teams' reaction."

Liverpool have six games remaining this season to smash through the 100-point barrier - they currently have 86 - starting at home to struggling Aston Villa on Sunday.

Joel Matip remains sidelined and Dejan Lovren is a doubt having missed the City defeat with a knock, with Klopp contemplating rotating his resources for the second of four matches in 14 days.

The Reds boss sealed back-to-back titles during his time at Borussia Dortmund having followed their 2010/11 triumph by overcoming a poor start to the next campaign to go unbeaten for the final 28 games and beat Bayern Munich into second place by eight points.

"We didn't do anything that different, no," he said. "We lost a player, Nuri Sahin, that year and then brought in Ilkay Gundogan, who obviously was not a bad replacement.

"What we did do is we trained hard, we were positive about our future but we didn't expect from ourselves to win the league again. There was a chance, but the big competitor was Bayern Munich and usually if you beat them they strike back with all they have. That year was no different.

"After five matchdays, I'm pretty sure were were about seventh in the league. The media in Germany were throwing at us everything they could find. They were saying we had lost focus, we weren't greedy enough any more, were still celebrating, all the obvious rubbish.

"And then we won a game away at Mainz 2-1 with a really scrappy goal. We knew in that moment that was for us the step in that season because we were not bad at the beginning, we just didn't get the results.

"From that moment the team went on and broke all records at that time in Germany, 81 points at the end, not losing for 20-odd games. It's because we were still good, and the boys were 100% on it."

Klopp added: "It's not important that you won last year, it's about that you maybe can win next year. We never felt that we had to win the league to show the league we are still on it. There is still competition and all the other teams can improve. It was a great season, but at one moment everybody was criticising us.

"What I learned there is that I'm prepared for all the things you (the media) are going to say about us if next season doesn't start like it should start. But as long as I see in the eyes of my boys that they are ready, then it will have absolutely no influence on what we do."
