[REF WATCH] We asked "Preventive Officiating" author Randy Vogt for his take on the officiating of the Champions League final:

Referee Pedro Proenca and his officiating crew can be very happy with their performance during the final.

In the 53rd minute, a Bayern Munich goal was correctly disallowed for offside. A shot deflected off Chelsea defender Ashley Cole to Bayern’s Frank Ribery, who had been in an offside position when the ball was shot. Assistant referee Bertino Miranda correctly saw that Ribery had been less than a yard offside when the shot was taken. A good call by Miranda and a relatively easy one to make for a very experienced AR.

On a play such as this, the AR makes a mental note of the player(s) in an offside position at the taking of a shot, then raises the flag only if the offside player becomes involved in the play. It’s important to stress that if a defender redirects a pass or shot to an attacker in an offside position when the ball was passed or shot, it’s offside. But should a defender pass the ball to an attacker in an offside position, play continues as it is not offside.

AR Miranda’s performance was not perfect, however, as he and the additional assistant referee behind the goal line had the best view of Cole’s deliberate handling of the ball just outside the side of the penalty area in the 66th minute yet no foul was called.

In the third minute of overtime, Didier Drogba tripped Ribery in the penalty area and ref Proenca correctly whistled a penalty kick. The trip occurred a minute after Fernando Torres fell just inside the other penalty area. Watching live, I thought Torres went down rather easily and the one replay I saw was inconclusive if a foul had actually occurred.
