MADRID (REUTERS) - Real Madrid stormed into the Champions League quarter-final with a club record 9-2 aggregate success after Cristiano Ronaldo struck twice in a 3-1 win at home against Schalke 04 on Tuesday.

Real were virtually assured of a place in the last eight after thrashing the Bundesliga side 6-1 in Gelsenkirchen in the first leg and coach Carlo Ancelotti rested a host of regulars for the return at the Bernabeu with an eye on Sunday's La Liga "Clasico" against Barcelona.

Gareth Bale set up Ronaldo for Real's 21st-minute opener and Schalke levelled 10 minutes later when a long-range Tim Hoogland effort deflected off Sergio Ramos and bounced past the stranded Iker Casillas.

Ronaldo took his tally in this edition of Europe's elite club competition to 13 goals with his second of the night in the 74th minute. Alvaro Morata added a third for Real a minute later after a Ronaldo effort came back off the crossbar.

It was Real's biggest aggregate Champions League win after beating Apoel Nicosia 8-2 in 2011-2012.
