Has anyone been able to benefit from diagonal pass ?

Hey guys, I use Eto'o and Sneijder with Jose Mourinho and although I'm very satisfied with these players, having such a good passer as a creative playmaker and such a fast hole player is incredible, but I haven't managed to make use specifically of the link up feature. As an LMF in a 4-2-3-1, Eto'o either cuts inside which make the diagonal pass impossible or he stays stuck to the fullback and doesn't run into space.

Should I switch to a 3-4-1-2 to make Eto'o hug the line and run in behind ? Any tips ?
