Los Blancos offered no mercy to their visitors as they exploded into life after the break, the Portuguese superstar scoring four while Pepe, Jese and Gareth Bale also on target
Real Madrid tore apart Celta Vigo, thanks in large part to a Cristiano Ronaldo hat-trick, as they made an explosive start to their efforts to repair their Primera Division title challenge with a 7-1 triumph.
Pepe opened the scoring in the run-up to half-time before Ronaldo stepped up a gear after the break, netting his first three goals in a period of less than 15 minutes before going on to hit a fourth.
Iago Aspas had scored a consolation goal for the visitors but Jese Rodriguez and Gareth Bale completed the rout with efforts of their own.
