I think Lewandowski to Barca is basically a done deal with all parties involved having no problems from a financial perspective. I think we'll be seeing news of his arrival at Barcelona for at least the next few hours.
I know at his age, City has a policy not to sign players over 30 years old. But I think they're missing out on somebody who could potentially bring them the UCL trophy. Just check his performances in the UCL with Barca next season. He'll be involved in the most crucial goals.
