With only Tottenham to win the best way to hedge both parlay is to take Arsenal +0.5 or Arsenal/Draw (double chance) and it'll cut a portion of your profits since Arsenal is the slight favs in this matchup.
In the first parlay the expected payout is around $770~ and the odds on Arsenal/Draw is at 1.33 so the optimal bet size would be around $560(BTC.013~). In this scenario you'll walk away with a $150(BTC.0035) profit no matter what happens.
In the second parlay the expected payout is around $3600 and with the given odds the optimal bet size is around $2750(BTC.065~). Your expected profit in this parlay is around $800(BTC.019) basically you have to bet a lot on the other side.
That being said I would have never put Spurs victory on those tickets. I am expecting Arsenal to win today.
Also, don't you have option to cash out those tickets? If you do, why not cashing out one of them and leting the other ride. Choose which one based on amount of belief you have in Spurs. I would cash out both since I consider them shit, but I also expected Chelsea to win yesterday.
