i watch cebalos last summer with spain U21 and it's hard to say what position he plays but my impression is that he's like all-around player and he's the best when you give him space... so i will say he's best as ATM.
but that mean that we will replace hakan and jack but as i said, i will rather replace biglia because hakan looks more promising and useful for us, especially if you move him back in mid.
ofc it will be ideal to replace all of them for wc players but i doubt they will have that much money.
that's the other solution...
can't say that i'm big fan of hakan on LW because i want fast modern winger but this give you option to replace biglia
