Real Madrid midfielder Toni Kroos has praised Cristiano Ronaldo following a record-breaking weekend for the Portuguese.

Ronaldo netted his 23rd La Liga hat-trick on Saturday evening as Los Blancos made it 18 wins in a row with a 3-0 success over Celta Vigo at the Bernabeu.

"Cristiano Ronaldo is a really important player. He put in a very good match and was decisive once again. He's always a key player and I hope he keeps it up," Kroos told his club's official website.

Ronaldo has scored 23 league goals in just 13 games this season.
