Last year in the heat of the battle against Ferrari, Alonso slammed the team that made him a man (not to mention a champion) saying that their only goal is the Constructors' Championship, which is not that worthy. He was pretty selfish and unfair, requiering even more focus on his campain. He also negotiated with McLaren, allegedly, behind Flavio's and his team's back. Just wonderful.
Now, similar situation with him in McLaren - WCC is worthless; I demand special treatment; I can blackmale my team, I'm courting to Max....
In short, the guy is not a team player.
So, I can't understand how can Renault want him back and forgive his antics? Also, he'll demand No.1 status and that will be unfair to Heikki.
