Arsenal embark on a Europa League campaign when Cologne visit the Emirates tonight.
Arsenal boss Wenger has already said the Premier League is the priority for the Gunners this season.
The Frenchman is also not a fan of the Europa League winners earning a slot in the following year's Champions League - as Manchester United did last season - and would rather get there by breaking back into the top four.
Wenger has always played a changed team during Arsenal's League Cup ties and it is likely to be a similar story when Bundesliga side Cologne visit London.
Earlier, Everton play their first Europa League Group E match when they take on Italy's Atalanta in Reggio Emilia.
The contest is taking place at the Mapei Stadium in Reggio Emilia rather than at Atalanta's Stadio Atleti Azzurri d'Italia home, which is to be redeveloped to make it fit for European competition.
