Greenwood can play on the right to get his playing time. Why do I need to repeat this again?
Because you have not thought beyond 18 months. Basically, your plan is to sign Haaland and tell Greenwood to forget about be a striker and become a winger.
Greenwood can play on the right to get his ‘playing time’ while waiting for Ighalo to move on, but not while waiting for Haaland. If you sign Haaland, unless he becomes a flop, Greenwood is no longer a striker. Whether now, or in 2 or 3 years when Haaland is just a 22 year old striker. What happens to him then? How about getting one of the world’s best young wingers, so that we can have one of the world’s best young wingers AND one of the world’s best young strikers (which we already do), instead of opting to have the world’s two best young strikers, with one of them competing with Dan James on the wing?
