Think the AM spots could be highly contested (or rotated if you prefer) whether Eriksen stays or goes.
Son, Moura, Lo Celso, Dele, Lamela, Sessegnon…..and Eriksen.
Of course, Lo Celso could spend some time at CM, but imo its more likely he spends the majority of his time as an AM (and assuming we play 4231), not all the above can play most games.
And Lamela has started the season brightly, so whilst I might have assumed he would rarely be an A team option in the last couple of seasons, that may not be the correct assumption atm. And with Sessegnon having made 30 appearances in PL last season, its reasonable to expect to see him in maybe a third of the games we play.
So provided we don't get too many injuries, the competition for forward line spots could be most intense for years. Good for the club.
