Considering Saka is preferred to Grealish by Southgate and pretty much the entire country for the right hand side, its a really bad take to suggest any sort of parity between Saka and Cole Palmer. Palmer isnt established and considered a key player for you yet. They are also of relative ages.
I don't know what you're waffling on about. I simply made the point that we have an extremely talented player already struggling for game time. And signing Saka, or anyone other player in that role, won't help him one bit.
