Well there are several sources, but Man. United are apparently close to signing Ajax midfielder Christain Eriksen. If we sign Eriksen, who i think is a very good attacking midfielder (aged 20) then i don't think we will sign Lucas Moura, who is also an extremely promising player. What do you think?

He is an amazing player. Best of luck united.
