Champions League Review: Referees with good performance in final 4 round of 16 matches

Welcome to the Champions League Review, where I give you my take on the crucial calls in recent Champions League action.

Monaco 0-2 Arsenal (Monaco 3-3 on away goals)                     Referee: Svein Oddvar Moen (Norway)
Overall, a strong effort from Moen, though his assistant may have gotten a key 23' offsides call wrong. Much of the talk from the refereeing side revolved around Alexis Sanchez's yellow card for diving.
42nd Minute: Arsenal's Alexis Sanchez goes down in the box, and Moen is quick to call a dive and give Sanchez a yellow. If you ask me, this play was in between a dive and a penalty, as there was enough contact for Sanchez to go down but not enough for a penalty. Play on would have been the correct call in my book

Atletico Madrid 1(3)-0(2) Bayer Leverkusen                             Referee: Nicola Rizzoli (Italy)
Rizzoli was up to his excellent standard besides maybe missing a knock to the face of Raul Garcia. Nothing much to go into detail about.

Barcelona 1-0 Manchester City (Barcelona 3-1)                         Referee: Gianluca Rocchi (Italy)
Rocchi was quite simply up to the task of a critical Champions League Match.
77th Minute: Barcelona's Gerard Pique clearly trips up Sergio Agüero in the box. Good penalty call by Rocchi. City would fail to capitalize, however.

Borussia Dortmund 0-3 Juventus (Juventus 5-1)                         Referee: Milorad Mažić (Serbia)
The veteran Serb had an easy night with no controversy. Very strong performance.
