Real Madrid got their UEFA Champions League campaign off to a great start, as they comfortably defeated APOEL by a 3-0 scoreline to ensure they went top of Group H, with Tottenham, Dortmund and APOEL following them.Cristiano Ronaldo scored 12 minutes into his return, although APOEL ensured it was a dull first half. Ronaldo scored from the penalty spot in the 51st minute before Sergio Ramos ended the contest with a well-taken goal in the 61st minute.Here are the major talking points from the game:#1 Madrid's defenders are more than just destroyersA large part of the reason Madrid have been so dominant in the last couple of seasons is the offensive output of their defenders. Tonight was no different.Dani Carvajal and Marcelo were a constant threat, especially in the second half, with their crosses into the box causing APOEL plenty of trouble as Ronaldo and Bale competed for headers in the centre.However, it was Sergio Ramos who stole the show in the second half with a quite impressive goal. Beginning the move in Madrid's own half, the Spanish defender then produced a superb overhead kick to ensure all three points went to Los Blancos. His appetite for goals is incomparable and he will surely add to the 83 goals he's scored for club and country in this Champions League campaign.Who's to say if it will be in injury time of the final?Most Champions League assists by defenders since the start of 2016/17:Dani Carvajal (5)Dani AlvesLayvin KurzawaBenjamin Mendy (all 4) pic.twitter.com/Q3lthCP9QW— Squawka Football (@Squawka) September 13, 2017Sergio Ramos: Has now scored at least one goal in six of the last seven Champions League seasons.
