If rumors are all in right direction, situation seem quite clear: with Neuville that will be key point of the market; if he will go really to citroen Ott will potencially have 2 open doors (3 with m-sport)
i'm also agree that duration of contract will have big influence on his decision. Toyota will be for sure a nice challenge with possibility to grow up the team around him and surely will give him long contract; also hyundai too could decide to give him atleast 2 years contract, in this case will be not easy to decide which option catch.
As big fan of Ott hope he will take the right one.
