White and Jesus will be hard to sell because of injury issues. Jesus may be worth selling with only a nominal fee or even buying out because the roster slot may be more valuable than the player. White I think is so good when fit - and therefore worth a lot on the market if proven fit - that I would keep him another year to try to re-establish value.
I would personally keep Martinelli unless we got offered crazy money. He's a limited footballer but he's incredibly useful in open games (ie, CL) and as a defensive replacement on the wing.
Trossard for me is up to the player. If he wants to stay on a year-by-year deal he can stay, if he wants to leave he can leave. We're not getting serious money for him given age and only one year remaining on contract.
I think the other big issue IMO is Norgaard's spot. Do we keep him as someone who is happy to be a back up, replace him with someone like Tonali who will play lots of minutes now (so that we really have a 3 man rotation for 2 spots), or replace him with someone like Bouaddi who is for the future?
Finally, I would be interested in seeing if there's a loan for MLS where he would play as a midfielder.
