Conte left Juve under not so different circumstances , there have been grumblings about United's transfer activity too with all those targets falling through. The market for strikers is rough, if you take out Barca,Real, Bayern, PSG and Juve who have the top strikers in this market you are left with Aubamayeng, Icardi, Morata, and Belotti as the strikers that have been identified as potential targets. Outside of them the market is thinning out unless a team can identify a striker with potential and ready for a break out season.
