After making 15 league appearances this season for Norwich, goalkeeper Mark Bunn has somewhat challenged John Ruddys number one shirt and the spot between the sticks. Bunn will no doubt get the nod again in the game against United at the weekend, but could face a huge test against United striker Wayne Rooney. With Robin van Persie having been given the green light for the recent Prem games, Fergie will look to rest him for the clash against Madrid on Tuesday night. Wayne Rooney and Javier Hernandez will likely be the strike force and will cause Bunn huge problems, especially with the likes of Ryan Giggs and Michael Carrick supplying the play. Rooney has scored just ten league goals this season leaving him nine behind United's top goalscorer Robin van Persie, who has by far been United's top player this season.
