there are conflicting reports. the other day some other media outlet said that locatelli's price is set at 30m, the clubs already agreed on that, and sassuolo only accepts cash, and no loan+obligation deal or counterparts like hans. (not to mention that loan+obligation is technically a sale and there's no point refusing it, especially between two clubs with good relations, but let's just ignore that.) now an other journalist reports that a mega offer is required. tomorrow an other will report that he's unsellable. then rinse, repeat.
either way, a 30m offer for locatelli (which might or might not exist) isn't lowballing by any means.
