Those two seasons when he won the treble and double made his ego swell up quite a bit.
What made it worse is we didn't have the Midfield players to finally give him some actual competition until recently. These days the guy is really full of himself, just go read his interviews, he still doesn't get why he ends up getting benched.
He will never realize his decline, nor the fact he didn't get a second contract extension he kept begging for or realize why coaches are starting to use other options now. He's believes everything that is happening is unfair and still thinks this is 2014/15 when he was at his peak.
