Manchester United are reportedly aiming to repeat their success of bringing Cristiano Ronaldo back to Old Trafford as they attempt to sign Robert Lewandowski.
The Polish striker looks highly likely to leave Bayern Munich this summer despite still having one year left to run on his contract at the Allianz Arena.
He has expressed his desire for a fresh challenge following eight years in Bavaria, with Catalan giants Barcelona having emerged as prime candidates for his services should he leave.
