The 22-year old Germany international is content at Dortmund for now but suggests one day he would love to make the move to the Premier League or La Liga.
"It is not reprehensible to answer such questions (of a future career in England or Spain) with 'yes',” he told Bild.
"Everyone has a childhood dream on what he would like to achieve one day and my dream always was to play in England or Spain.”
On a new Dortmund deal, Gundogan added: "I am 100 per cent sure that I will still be with Dortmund next season.
"Rumours do not really affect me. I still have two more years on my contract with Dortmund and I know what I have at this incredible club.
"It is very likely that I will sign a new contract, although it obviously depends on how talks go."
