The two players are leaving Queens Park Rangers this summer.
It was confirmed on Monday that both players would be leaving the club this summer as their contracts have not been renewed.
They were among seven who will be heading to pastures new, as the Dutchman takes charge of his first summer transfer window at the club.
Both players are something of heroes among the Rangers faithful, especially Hill, and Hasselbaink says it is now time for new heroes to step forward.
“There is no disguising we have had some very difficult decisions to make,” he told qpr.co.uk.
“Clint and Ale are QPR stalwarts who have given outstanding effort and commitment to the club, but now is the time to try to make new heroes for the supporters.”
Whether both players find new clubs in the Championship remains to be seen, although there are sure to be teams interested in both.
Their futures are uncertain, but what is not so uncertain is the fact that Hasselbaink is planning a major overhaul of the squad at his disposal.
It is sorely needed, too, considering the disappointing campaign they have had, and the Dutchman will be hoping he can do a better job of signings than they have managed in the past.
