who should replace walcott in arsenal XI?

We have rosciky ox poldi gnabry 2 fill the gap

in my opinion its poldi-lw cazorla moves to right

Bcuz,walcott should be replaced by a similar goal threat..

gnabry is good but not a threat and inexperienced

ox has pace and skill but couldnt put in cross or finish like walcott or poldi

putting in rosciky would change the play into a defensive type and possesion...no goal threat

wats ur opinion and who will play today
