"The year of Luka Modric has been fundamental, but I would give it to Cristiano Ronaldo for the merits of last year", said the Brazilian.
Modric, who won the Golden Ball at the World Cup after leading Croatia to the final, created Madrid's second goal with a perfectly weighted pass for Gareth Bale.
"With Luka, Toni [Kroos] and Isco we have known each other for a long time, the quality they have is impressive, everything is easier, I know them and we feel very comfortable".
Marco Asensio came on for Bale just after the hour mark and almost had Real's third in the 79th minute only to see Olsen save his close-range shot after his neat turn left him with just the Roma keeper to beat.

If a team create 30 chances then they deserve full credit, particularly against a side like Roma.
Mohamed Salah and Harry Kane were also linked with a move to Spain in the summer transfer window, but that too did not happen.
