Found this b8 s4 fo4 cheap but it needs work

Found this s4 for cheap but it needs a lot. The car wont go into any of the gears when its on. It goes into all of them when parked and thats the only way to get it moving. When it gets going it goes into gears but its noticesbly more difficult than my s4. I do think i hear a chain rattle when it starts up for about 3-5 seconds. Is it possible its just a clutch cylinder issue or is it most likely a problem with the clutch? I hear a sound when moving and I couldnt tell if it wad the clutch scraping the flywheel, an exhaust leak swooshing sound or possibly timing chain because Im not familiar with what the chain should sound like if its on the way out or god forbid already slipped.
