However, they have reached a cup final and semi final this term, with Arteta not wanting to talk too much about all the money they have spent.
He stated: I'm not the person to talk about that. I can talk about what we have done but not about what other clubs are doing. It is entirely up to them. They will have their vision and be very clear in how they want to get there."
On getting a billion to spend himself, he added: It depends. I like a lot what I have. I'm very pleased with that."
On whether Chelsea show that spending does not correlate to success: Look, that is a very short sample. If you look at the history of the Premier League in the last 20 years at the ones that have spent the most and what has happened there is a big relation. Depending on how you look at it."
And on whether Chelsea will eventually be successful, he finished: I am convinced they will. With that squad, yes. And with the manager they have."
