I wouldn't be certain of that. Poch had no problem doing it with Trippier vs Walker, and Davies vs Rose. When Dele came in he knew the deal. Poch is clearly more scared of upsetting Kane than pleasing a back-up like Wilson. I love Poch but I'm not buying the excuse of they won't take a seat on the bench. You don't want to be signing players that do want to take a seat on the bench. Poch does better with understudies than established or older first team players anyway. Janssen and Llorente clearly haven't adapted to English football. Wilson, or okay yes, someone younger or from lower leagues or even academy out on loan would be a perfect option. Failing that, having no one at all and using Son as a #9 is better than having two deadwood players holding up squad numbers or wages with no sign of progression. But in all honesty the problem with them both is that they were happy with being on the bench, and it could be risking the same with a signing like Arnautovic in my opinion, only difference being a couple more PL goals.
