Arteta has stated that he has no doubts about Saliba's readiness to return to the team, citing the positive progress he has made. The team is set to face Slavia Prague in a match, and it remains to be seen whether Saliba will feature in the lineup. Arteta's confidence in Saliba's readiness is a positive sign for the team, and fans will be eager to see the defender back in action.
