Manchester United have joined the interest for unsettled Bayern Munich striker Robert Lewandowski.

The Sun says United have joined Chelsea in the pursuit of Lewandowski.

The Polish international has been regarded as one of the best strikers in world football over the last few years after his impressive form in the Bundesliga.

Lewandowski's German agent Maik Barthel said: “Robert told me that he got no support and that the coach gave no call to help him in the last game to win the top-scorer title.

“He was disappointed as I have never seen him before.

“He really hoped that the team would support him proactively."

Spanish pundit Guillem Balague tweeted: "Both Chelsea and MUFC have spoken to his agents. London preferred choice, but MUFC, very keen and last chat was yesterday".
