Well, ABOLA says that Mourinho is looking at alternatives for Filipe Luis. On the list there is: Fábio Coentrão (Real Madrid), Moreno (Sevilha), Davies (Swansea), Rodríguez (Wolfsburg) and Rojo (Sporting). http://abola.pt/nnh/ver.aspx?id=487165
I would think a PL loan would be suitable. The guy played at the World cup, and had very solid performances and yet we still loan him to a Championship club!!!!
