Stoke City have qualified for the Europa League after Manchester City wrapped up their place in the top four.
The Potters' FA Cup final opponents secured Champions League football with a win over Tottenham on Tuesday, meaning that Stoke will play in Europe next season regardless of the result on Saturday at Wembley.
Boss Tony Pulis told reporters: "It's dreamland. Who would have thought it?
"But the important thing now is that everybody keeps their feet on the ground and realise what a ride we are on.
"As quickly as you rise, if you take your eye off the ball, you can just as quickly fall.
"My message to everybody is enjoy it and get the most out of it, but don't forget where we've come from and what it has taken to get where we are… a great togetherness, a terrific spirit and loads of hard work."It will be only the third time the club has been in European competition in their 148-year history and the first time for nearly 40 years.
Tony Waddington's side took on Kaiserslautern in 1972 and faced Ajax two seasons later.
Stoke have already been told that they will enter the Europa League at the fourth qualifying round, halfway through August, if they beat Manchester City in the FA Cup final on Saturday.
However, if they lost the final to favourites City, they would enter at the third qualifying stage of the competition.
When the Potters played Kaiserslautern in 1972, they won the first leg 3-1 at the Victoria Ground but the German side turned it around in the second leg to progress to the next round.
Two years later, City were eliminated on the away goals rule to Dutch giants Ajax, who held Stoke to a 1-1 draw at the Victoria Ground in front of 37,398. The return leg was a goalless draw in Amsterdam.
