I believe Sherrif can no longer beat real madrid for the second round match of the group stage. After all, Real Madrid will certainly learn from its mistake in the previous match and will correct its mistake to win this match. I'm sure Real Madrid will win even if this match is played at the Sherrif's home. But before that, we might need to know if Real Madrid managed to beat Shakhtar Donetsk.
Both teams , Shakhtar Donetsk and Sherrif when they have a good day can surprise and playing very well against every big Teams.
On the paper for sure it looks like that they normaly have no chance against Real Madrid , but i would not underestimate them.
Its hard to play against this 2 Clubs , specialy when they playing in the Champions League.
