Don't disagree with that, but it's the same with the penalty, it was punishing a players stupidity but harsh but it was a mistake by Monreal with a mistimed attempt to get the ball which created the situation in the 1st place
Both can be deemed correct but both are harsh, the sending off though changed the game as Leicester could barely get out of their half after it, so we certainly had the best of it today, that's ignoring the penalty they should have had when Mahrez was caught.
