Manchester United will reportedly move for Robert Lewandowski if they suffer defeat their bid to bring Cristiano Ronaldo back to Old Trafford before the transfer deadline.
According to The Telegraph, the Premier League champions will actively pursue the Real Madrid superstar when David Moyes begins his official duties later this month, but United are not entirely confident of prising him away from the Santiago Bernabeu.
Most recent reports suggest Ronaldo has been advised by those close to him to run down his current deal with Real Madrid in order to secure a free transfer back to Manchester United when the contract expires in 2015.
Should Manchester United be unable to capture Ronaldo in the current transfer window, then the Red Devils will reportedly focus their attention on recruiting Borussia Dortmund striker Robert Lewandowski.
Lewandowski had been expected to join Bayern Munich, but BVB have been reluctant to allow the player to join the Champions League winners following the departure of Mario Götze to the Allianz Arena.
