Sheffield United manager Chris Wilder concedes they face losing Sander Berge this summer.
Berge has been a revelation in his first season in England.
Speaking to Norwegian broadcaster TV2 last week at Bramall Lane as part of the club's commitments to Premier League rights holders, Wilder said: "I think this [Sheffield United] has always been a springboard for Sander.
"He wants to play at the highest level, he wants to play Champions League regularly and he wants to play for a top team.
“We gave him an opportunity to show off his skills and he has taken it. If he plays well, he makes us a better team, but I know that day will come.
“I know Sander won't be here until he's 32, but we enjoy working with him and hopefully he has a few games left as a Sheffield United player. I understand, if he goes and if it happens, then it happens with our blessing.
“I wish Sander all the best. Do I think he can play for a top club? Absolutely, but for that to happen, he has to keep doing well here."
The 23-year-old midfielder is currently in rehabilitation for a hamstring injury suffered in the 3-2 defeat to Man United in December.
