Bilic says that the way the target-man occupied Chelsea's two centre-backs, John Terry and Gary Cahill, was hugely impressive and he was delighted with the way the England international played.
“Andy is a big player for us, and also for England. He is special," the Croatian manager said.
“He gives us a lot of options. It’s not just long balls, he is a great player, his quality has never been in doubt. We just needed to get him fit.
“Now we are in a really good situation regarding his fitness and he should be fit and ready for the long-term.
“We will have a lot of benefits from having him fit. It is not just his work inside the box but also his contribution outside the box. His pressing was amazing; his work-rate was excellent."
Carroll has been eased back into first-team life at West Ham, after a spate of injuries had halted his progress at Upton Park.
The 26-year-old has struggled to steer clear of the treatment table ever since moving to the London club, but he is back to full health again now.
His performance against Chelsea proved just how dangerous he can be when available for selection, and Bilic will be hoping to keep the powerful forward fit for the future.
West Ham's win over Chelsea has pushed them up to third in the Premier League table, with Bilic's side one of the Premier League's most impressive teams over the first 10 games of the season.
