The formations talked about 4 1 3 1 1 is not how we play. we play eiher 44 1 1 or maybe if you were being detailed 4 2 3 1.
4231 is our best formation as it allows us to utailse our best players in the area we do damage.
Hibbo Jags J-Lo Baines
Arteta Felli
RW Cahill Peanut
Yak
If we get Mbia surely it means that he will be competition for felli rodwell in the DM role and also allow felli to be competition in the cahill role.
Therefore I would say RW is our priority I also think ossie should be considered competition for arteta as I think that is his best role.
