Manchester United have approached Bayern Munich over a deal for centre-back Jerome Boateng, according to reports in Germany.

The Premier League side believe their Bundesliga counterparts will ask for around £45m to allow the Germany international to leave the Allianz Arena.

It is understood that Boateng – who spent a season at United’s bitter rivals Manchester City – could be open to a move to Old Trafford.

However, United are not the only side who are interested in the 73-cap international. Bayern chief executive Karl-Heinz Rummenigge said last month that Boateng was in talks with PSG.

He is the latest centre-back United have shown an interest in this summer, with Jose Mourinho looking to strengthen his defence before Thursday’s transfer deadline.
