Well maybe he could have shown some more yellow to Slovan players in the first half, but he didn't and all went well.
Clattenburg did book a Slovan player for a dive.
Ajax, once the bedrock of total football a system where (almost) all players could play on all positions, now seems to be a one-man-team. The one man - Uruguayan Luis Suares - had all the shots on goal, scored four of the five goals and did most of the work.
And did I see this right? Does Slovan play with only right legged players? No ambidextrousity there.
