Slightly surprised that Del Cerro Grande has a game, he does have history with Guardiola IIRC.
I am also surprised with Del Cerro getting a game.
The final... has to be Kuipers.
In my opinion Kuipers has a chance only if Real Madrid get to the final and Lahoz can't be the referee. Lahoz has a decent chance of getting it if he recovers from his muscle injury.
Obviously Kuipers is the better referee, but he already has a CL final under his belt.
