It's a risk for sure. Our record without Albrighton is dire and I always feel he gives the side such a great balance, protecting the defence and shutting out opposition counter-attacks and dropping back allowing Mahrez to go join the attack from the other flank.
Schlupp isn't as good as Albrighton defensively and doesn't allow the same support to Kante and Drinkwater when Mahrez goes forward, but he does offer pace. And I assume that's the reason he's in given Vardy's absense.
It's a risk for sure, but Claudio's done enough to earn my trust this season.
