The 21-year-old Werder Bremen star has been linked with some of Europe’s biggest clubs after impressing for Germany at the World Cup finals.
“There are four or five clubs in Europe that you would have to say as a player would be a dream to play for,” the youngster said in the Daily Star Sunday.
“Manchester United and Chelsea are very much two of them.
“When you are looking at moving clubs it’s impossible not to pay attention to the Premier League and even more impossible not to pay attention to Manchester United and Chelsea.”
He added: “I am a winner and, when I am looking for a new club, I simply look at where I can be the most successful and where I can win the most trophies.
“If you look at the recent history of Manchester United and Chelsea then it’s clear that a player can be very successful there.
“Of course clubs like Real Madrid and Barcelona are of huge interest and the Premier League’s top two clubs are of serious interest to me when the time comes.”
He added: “I am under contract with Werder for another year and it is impossible for me to say if a deal will be done this summer.
“They may decide that they want to keep me for another season or they may decide to sell me this summer so they can get some money for me. That is up to the club.”
