Injury news on the West Ham trio heading into the late Autumn and Winter months.
Playmaker Song will resume training with the rest of his team-mates next week and has completed 'most' of his rehab work.
Meanwhile, defender Henry will resume team training during the first week of November, while O'Brien will feature for West Ham's Under-21s next Monday. All three bits of news are encouraging when it comes to the east London side's current squad depth.
Indeed, Vandenbroucke told the West Ham site: "Alex Song has done very well and has completed most of his training with the rehab fitness coach. He will resume team training next week.
"Joey O'Brien has trained for two weeks and will play for the Under-21s at the Boleyn Ground on Monday. Doneil Henry is continuing his rehabilitation and will resume team training the first week of November."
Vandenbroucke finished by emphasising the need to have all of West Ham's injured players back for the busy Christmas period and that will naturally be a big aim for every medical department in the Premier League.
As for matters more in the short term, the Hammers have every chance of beating Chelsea this Saturday afternoon but boss Slaven Bilic has shown an understandably cautious approach during his pre-match press conferences.
West Ham haven't yet shone at home and would probably much rather be playing Jose Mourinho's men at Stamford Bridge based on recent form.
