2) Ander Herrera/Ilkay Gundogan (Manchester United)
Two players who could complement each other really well for Manchester United, Ander Herrera has had a great first season at Old Trafford and could be joined this summer by Borussia Dortmund star Ilkay Gundogan. The German international is a class act with plenty of qualities to his game, and looks the ideal long-term replacement for Michael Carrick in that deep-lying role.
