In his column for the Telegraph, Mourinho wrote: "If Barcelona will miss Dani, Man United will miss Darren Fletcher. Fletcher is more important than people think. His work in midfield, especially in the midfield 'wars', in crucial matches is very important. Man United will miss his pace and aggression in defensive actions: he 'eats' opponents in defensive transition.
"In possession he is not magic like Ryan Giggs or a superb passer like Paul Scholes, but he is dynamic, he makes movements, he creates spaces. I like him a lot and I believe it is not an easy decision to replace him. I believe Xavi and Andres Iniesta are happy Fletch is not playing."
