The Gunners are preparing to host the Bulgarian side at The Emirates as they bid to continue their recent good run of form.
Walcott scored twice as Arsene Wenger’s men recorded a 3-2 victory over Swansea City in the Premier League over the weekend to make it six wins in a row in the top flight.
The three points lifted Arsenal up to second place in the table and level on points with leaders Manchester City after eight games of the season.
Arsenal are now turning their attentions back to Champions League affairs as they bid to take a step closer towards the knockout phase of Europe’s elite club competition.
And Walcott feels that Arsenal will be expected to ease to victory against the visitors on Wednesday night.
Walcott is quoted as saying by The Daily Star: “I don’t think they will be looking forward to playing us, that’s for sure.
“Especially with the way we’re playing and the amount of goals we’ve scored this season already. I am really looking forward to Wednesday now.
“Everyone will say that this is a fixture we should win and we know we should win it.”
