Man United boss Jose Mourinho could be frustrated by Pierre-Emerick Aubameyang transfer

Kasper Dolberg is wanted by Man United and Chelsea

The Mirror claim Borussia Dortmund are also keen on the young striker.

Dortmund star Pierre-Emerick Aubameyang is currently at the Africa Cup of Nations and doubts remain about his long-term future in the Bundesliga.

It's suggested Dolberg is viewed as an ideal replacement for the Gabon international if he departs.

The Sun claim United aren't the only Premier League side who are keen to secure his services.

Manchester City and Chelsea are also reportedly in the hunt.

The 19-year-old has been making headlines in Holland and bagged a hat-trick inside 18 minutes against NEC Nijmegen last year just days after making his international debut.

Respected scout John Steen Olsen first spotted Dolberg and has high hopes for the powerful target man.

In fact, the man who discovered Zlatan Ibrahimovic thinks he is the 'perfect' player.

He said: "Kasper is an extraordinary talent. I knew he would be a perfect player for Ajax."
