Sinclair faced former side Manchester City as Villa earned an admirable 0-0 draw against Manuel Pellegrini's side.
And Eyre feels Sinclair was forced to work against City and, generally, is often left unable to display his creative talents.
Eyre told BBC Radio Manchester: "It's not been Scott Sinclair's type of game where he can take the full-back on. It's more been about work rate. Scott likes to weave his magic but in the modern game it's difficult for him to show his skills."
In truth, it was about 'work rate' for the whole Aston Villa side as they earned a hard-fought 0-0 draw against Manchester City, who were top going into the game.
Even though Villa defended superbly throughout, City didn't ever look too much of a threat.
That was in part down to themselves but also Villa's effective closing down. There were so many last-ditch tackles and even opportunities to quickly hit City on the break.
It looks as though this is actually a good Aston Villa side that was simply held back by an incompetent manager in Tim Sherwood. But it's perhaps a little too soon to say that. Remi Garde earned a good point against Manchester City and he will obviously need to continue delivering considering Villa's current position.
