Of course, there is no way to know it. However, I look at his stats of the previous season, I do not see any indication of him being a prolific goal scorer for a sustained period of time. Was he a flash in the pen only? Costa is 29 years old, but looks like he was through a windmill, to me. If he comes, I assume a 5 year contract will be offered to him. Now, 29 plus 5 = 34 years. Lol.
