Real Madrid 3-2 Borussia Dortmund: 5 Talking Points

#3 Should Ronaldo's disallowed goal have been allowed to stand?

Cristiano Ronaldo will undoubtedly feel hard done by the linesman's decision

Cristiano Ronaldo had already made history by becoming the first player to find the net in each group stage fixture of a Champions League season. By doing so in with an excellent shot from the edge of the box after 12 minutes, the Portuguese forward also equalled Lionel Messi's record of 60 goals in the group stage of Europe's elite competition.

However, Ronaldo felt that he was harshly denied a goal in the 79th minute that would have seen him eclipse Messi's tally of goals scored in the group stages. A corner was flicked on by the head of Casemiro - or so it had seemed - before Ronaldo blasted it in, only to be flagged offside.

Real Madrid were unhappy on two fronts - first, by claiming that Ronaldo was level with the last man, and then by appealing that the ball was flicked on by a Dortmund player rather than Casemiro.

Though replays confirmed that the first ball indeed came off Casemiro, the offside call against Ronaldo looked controversial, as he looked to be just about level when the ball was played in his direction.

Nevertheless, the linesman has only a split second to make his decision and it is only a matter of waiting until next season when Ronaldo gets another crack at breaking the record.
