Yes I am. First teamers getting more or less similar game time as Xhaka, Chambers and Iwobi.
You toss in three red herrings (jenkinson, perez and campbell) to prove your point that we can only sell our players with great difficulty and to suggest that Xhaka, Iwobi and Chambers, therefore, have little to no value and should be allowed to leave for nothing. But the three you highlight (one of whom we've just sold) have played practically no games for us in the last 2 years, compared to the 135 or so premier league appearances for Xhaka, Iwobi and Chambers in the last two years.
I'm not suggesting these three are top quality players who can adorn any top 4 team's starting 11. But they have value, and can be sold and as such are investments/assets. To suggest otherwise is nonsense.
