Greif vs. Descamps

Fonseca’s choice of putting in Descamps instead of Greif for the Lens game has me puzzled.

I know the tradition of using the 2nd goalkeeper in the French Cup, but this was a quarter-final vs. a very good team – not a 2nd or 3rd division team earlier on.

I can’t help but think would have done better in the penalties, maybe even in the game.

Personally, I find Greif much better than Descamps.

Any good reason he was the goalkeeper this game?
