@Stefanovich,
It is not so late,we still have one month,not so long but enough to adjust some things.
Mbia doesn't need a year to get used to play with another teammate as central defenders,for me Bassong is not that much good and Bikey is so heavy,I prefer Mbia-Nkoulou,apart from that we can try out MBIA-CHEDJOU or again Nkoulou-Chedjou.
