Birmingham City boss Alex McLeish says they will have to deepen his squad with a Europa League campaign now to look forward to.
The Blues have been granted a licence to appear in the competition next season.
McLeish said: "We are looking also to build this summer. We've got Europe coming up as well.
"I spoke to my friend in Holland, Jan Wouters, and he said his team, FC Utrecht, ran out of steam after a brilliant start to the season when they played great stuff.
"They beat Celtic over two games, did quite well against Liverpool and Jan says they ran out of steam because of the Europa League campaign.
"That tells you we are going to have the resources to cope with all competitions, especially with the intensity of the Premier League.
"But, listen, I'm not even thinking about the recruitment stuff just now until we are mathematically safe."
