32 years old striker like Llorente will aware that he is not the first choice striker if he come, he will play only when needed and think he will accept it. We did that with Eto'o and Drogba couple of years ago. Our first choice striker will then compete with Batman week in week out. Not mentioning if one of them having long term injury. So, I don't see any problem with having 3 strikers like you said.
