CPM Tough to be so ruthless with an academy product but if he really attracts a £50m offer then it's the best thing for the club (and the player).
My view on this, is that every player has their price. Everyone speaks about Arsenal becoming a better selling club, but they're not willing to see players go when they're perhaps playing their best football. I can think of perhaps two or three instances where we've done this, and they're all players that came through the youth system (Willock, Martinez and Iwobi). We should've sold Maitland Niles in similar circumstances, but failed to do so (im not aftertiming here, we should've bitten Wolves' hands off).
Liverpool, a few seasons ago, were brilliant at maximising their assets. Harry WIlson, Rhian Brewster, Ryan Kent, Danny Ward, Dominic Solanke, Jordan Ibe...all went for ridiculous fees and have gone on to do next to nothing. They even sold players at the peak of their careers (Coutinho, Suarez) and trusted their scouting and recruitment, to build a squad capable of winning everything in Europe.
I don't think anyone on here is doubting Smith Rowe's ability (from what i've read anyway, and some seem to be over-reacting to this part), but we're yet to see him performing in this Arsenal side that's on a steep upwards trajectory in terms of where it's heading. He deserves every opportunity to regain his match fitness and play his way back into the side. What I do think some are perhaps under-estimating, is how difficult that will be for him, especially given how much Mikel seems to trust his starting XI. This is where my concern lies. The hope is, we continue blowing sides away early enough for him to get minutes again, and he recaptures that form. If that doesn't happen, and a side are willing to pay what you could consider a fair price, then I think Arsenal should listen to those offers and trust their recruitment process, which has almost been perfect these past 18 months.
