It wasn't shocking, but I think he has to take the gamble and go for it. We know Alonso can hit them in that exact spot.the keeper has to make assumptions and cover the area of the goal most likely to be aimed for.
The shot was totally perfect and as far away from Lloris as was physically possible
To say it was shocking can only be based on Lloris's inabilty to read the mind of the kicker, and his failure to know in advance which one was going to hit it.
