Yes & yes. Now, please show me some news sources you've seen that make it quite clear on that very strong chance of leaving.
Thus far it's only been a vague "argument" about image rights on his eventual contract renewal, and some even more vague media specualtion that if he doesn't renew, he'll get sold.
Apparently the cause for not celebrating his goals today was speculated by some as him feeling undervalued due to not getting a new contract with more money.

Kovacic too was heavily speculated and in the end signed till 2019.
This article, sorry to say, it's yet another speculation at best and worst, especially regarding Mauro.
