If he’s got any sort of knock I wouldn’t play him Leicester away so that he can definitely play on the Wednesday vs Watford. If he’s fit for Leicester, I would then rest him vs Watford. He can’t play both as he’ll break down, he always does.
The upside to resting him in one of the next 2 is that we could then start him for both of the home games. At that point it’s worth the risk of him breaking down vs Palace. Play him in both the aways and there’s very little chance we see him for the rest of the season.
