I think the "ticket to getting in this team is pressing" is critical. So long as we have any sorts of results, those coming off the bench will actually play with intensity off the ball.
Regarding his English, this is a big problem, and also very easily fixed. I don't understand how there isnt a system in place for language instruction that is built into how we set up new signings. You get nutritionists, you get people that help you get a house. Why the fuck don't we have people teaching English for the occupations where the occupation is football. Or if we do, why is it up to the player in some way. There shouldn't be any way he doesn't have any English by now.
There is an expectation here and I think the issue is that it doesn't show dedication on his part, but I don't think it should be a choice, because Nunez isn't the only player who you can imagine having an allergic reaction to a class.
All language takes is time. It doesn't require any theoretical understanding of anything. I don't care how thick anyone is, they all learned a language to the level required for football at about age 5.
