Not the best...

the match

The match is simple to resume. FCPorto on the offensive all match, Zenit always defending the draw and a great GK in the russian side.

Carballo

In my opinion he was, and sometimes he his, arrogant with players. There is no need of some gestures or expressions he uses. In the foul department he was reasonable, missing some fouls, but with good use of advantage most of the times. The biggest mistake was at minute 44 Fayzulin (ZEN) tackles Defour (FCP) in a way I consider it's an obvious situation of violent conduct. The referee didn't point for foul, just play on. Was a clear red situation. The player Defour was replaced at the end of first half and is injured, according the last news. Apart from that, he did a acceptable job, the match wasn't difficult. The group of assistants had a good performance.
