Absolutely - I agree on that part, it does sound like he's suggesting that the Treble was a nice time to leave. Although that does suggest that, like any decision, it's made up of multiple factors.
I was just saying that it's still quite possible that the 2/3 year contract offer could have been one of the factors that tipped him one way or the other - particularly as, rather than just being a year of money, the extra year might be more symbolic about showing how keen City were to keep him.
I have no idea if the 2/3 year thing is true - just saying it seems harsh to call people bullshitters when it's quite possible to have this interview, in perfectly good faith, and it still be true about the contract being a factor.
