It's not black and white, on one hand, Leicester had every right to ask for more money considering that it was the last days of the transfer window and that he's one of, if not the most important player for them.
Leicester are in no way to blame here.
At the same time we can understand the player. He was professional for a year and a half, gave his all for the team even after they held onto him last summer.
I don't think that his absence from training was a kind of rebellion against the club. I think it was a mix of not see a way back after he asked for a transfer and a frustration at the move not materializing. He took a week/10 days to clear his mind and came back. And as he said in his statement, he was in contact with Leicester and they knew about his whereabouts.
The speculation of the media made it into more than what it is.
And for the poster talking about 3 digits salary. Well, they are humans, we shouldn't expect players to act differently than us because they earn more.
City is the only culpable for me here. And I'm not saying that because they're our rivals. Merely because their approach was disgusting. They made a mess of the situation, they pulled away and let the lcfc handle the mess.
