Dunno about that. It's certainly based on very little evidence. How many games have Rafael and Herrera played together?
It's funny actually, the one United player Rafael seems to have had the best understanding with is Valencia himself. Even when Valencia lost his mojo as an attacking force completely, his link up play with Rafael was very good. I wonder if thye'll ever play in the same team again?
The QPR game there was fantastic chemistry between Rafa and Herrera.
Rafa's work is better off the ball than Valencia's and both Herrera and Rafa were looking to make both penetrative runs and ghost runs, not only creating space for each other but also dragging the opposition wide and creating space for Van Persie and Mata to operate around the area.
With that sort of panic and attention on that side of the field it in turn made space for Di Maria and Rooney to work the left channel with Daley Blind doing a good job of switching the play that day.
Again against West Ham they linked up well, this time Herrera would drift across their area as they were stretched by Rafa and he used the space to link well with Rooney around the area.
Valencia and Fellaini have been really solid on that side but it hasn't been nearly as dynamic.
