Robert Lewandowski (Bayern Munich)
Next up is a man who has been linked with a move to Old Trafford on several occasions in the past, not to mention just about every other top European club in the world, because of his exploits in the Bundesliga for the German champions.
Lewandowski is 30 now, but he is still standing out in a Bayern team which has struggled at the start of the new season, scoring five goals in his first seven league appearances this term.
165 goals in 205 appearances in total for the Bavarian giants tells you all you need to know about this man’s credentials and Mourinho might be tempted to mount a bid for a player with his experience and quality at the highest level in the new year.
The Polish striker is strong, great in the air and above all else absolutely deadly in the box, which makes him the perfect replacement for the misfiring lummox Lukaku.
He is contracted to Bayern until 2021 but if United were to move for him in the new year he might be tempted to try his hand in English football, where his attributes would be very well suited, to say the least.
