McGinn is not going anywhere, likely even if we get relegated. PL teams won't exactly be lining up to sign him with his form this season despite an early flurry. Mings too hasn't exactly covered himself in glory. Only one I can see is Jack, because he's actually good enough to attract interest from teams that can prize him away from his boyhood club.
But then that would mean another £80m or so on top of the TV money, and as much as it hurts to say, that could be a blessing in disguise. But I agree, I hope that the owners flex their muscles. Who knows, if they reassure Jack that we'll be making major moved he might give it 1 more season. If we find ourselves battling relegation again, he can leave with our blessings.
