Thomas Müller (Bayern Munich)
Thomas Muller, who is surprisingly not in great form this season due to low football playing time with Bayern Munich, would be another exciting addition to United squad. The Germany World Cup winner has won series of Bundesliga titles with the Bavarian whilst the Champions League as well and could be up for a new challenge in England. Muller has 8 goals and has 15 assists for his team-mates in across all competition this season. The 27-year-old is tied with Bayern till 2021. Muller would not cost United a big sum out of their total £250m that Mourinho is determined to spend. He is a versatile player and will solve more than one problem at Old Trafford this summer.
