Wells he bid for 30 million for Suarez so to me it looks like he does want a striker. You don't bid double your transfer record if you want to gamble with Giroud. So I think he does want one, wether he gets one is a different matter.
It does make sense for a manager to be involved but only to a point. If the board are saying we have the money don't worry, and he's worrying, that is not sensible. The board then need to tell him to leave it to them. He's identified a target, they will get him the target.
