Manchester United have tabled a contract offer to Borussia Dortmund striker Robert Lewandowski.

The Daily Star says United are believed to have offered Lewandowski a four-year deal worth around £70,000 a week.

Sir Alex Ferguson watched the 23-year-old hitman in action several times last season and wants him to link up with Wayne Rooney.

Lewandowski plundered 30 goals for Borussia this season to help them secure back-to-back titles.
