As things stand today Unai Emery has four new signings that he can use from the six that joined the club in the summer transfer window.
William Saliba remains with St Etienne on a years loan and Kieran Tierney is injured, however, Gabriel Martinelli, David Luiz, Nicolas Pepe and Dani Ceballos are all available for Emery to utilise.
Martinelli is not a major issue, he was never expected to be a first-team regular, though he will probably feature fairly often but Luiz, Pepe and Ceballos are expected to be heavily involved.
And that is where there are potential problems.
As an example, Luiz has been brought in to shore up the defence but that defence enjoyed a clean sheet last week against Newcastle and so to integrate Luiz, Emery will either have to drop one of the central defenders, change the formation or play the Brazilian in a different role, defensive midfielder maybe. Point is, these are risky options.
Same in the midfield, where does Ceballos come in? will he play the role that Ozil or Mkhitaryan are normally deployed in or is he used in a more traditional midfield role?
Of course, it is good to have these issues, much better to have an abundance of quality talent to choose from than have serious gaps and weaknesses to deal with but having a richness of talent does bring with it the temptation to play them all at the same time.
And that is the big temptation that Emery must avoid, the temptation to fit in Pepe, Luiz and Ceballos for the sake of it.
What is best for the team must come first and not that of the individual.
