Did the MLS All-Stars deserve to be called for a penalty vs. Arsenal?

Joel Campbell - Arsenal - MLS All-Star

The MLS All-Stars fell behind early against Arsenal on Thursday night, going down 1-0 after Costa Rican international Joel Campbell buried a penalty kick in the 11th minute.

Montreal Impact defender Laurent Ciman was whistled for the PK, clattering into Campbell from behind after goalkeeper Andre Blake was caught off his line attempting to grab onto a bouncing ball. Referee Chris Penso quickly pointed to the spot, much to the protestations of Ciman and his MLS teammates.

What did you think of the call? Did Penso get it right? Let us know.
