Carroll’s persistent injury problems have plagued his time at West Ham to date.
The target man forward has only managed to play more than 20 times in the Premier League once in the four seasons he has spent at West Ham to date.
And while Bilic admits that he won’t ever give up on the England international, the Croatian boss has suggested that Carroll must find a way to stay off the treatment table.
"He is so valuable for us, has a big impact on our game, he is very important. When he isn’t available, we really feel it," Bilic said.
"I will never give up on him but his injury record has to improve."
Carroll has played only 18 matches for West Ham this season, and scored seven times.
The former Liverpool and Newcastle United man has been a potent weapon when he has been fit, but his inability to stay off the treatment table has been a frustration.
West Ham are expected to bring in a new striker this summer, meaning Carroll could face a fight to win his place in Bilic’s team back when he does return to fitness.
