Well personally speaking I would give it to christiano Ronaldo still because I think Ronaldo deserve it to Lukas modric.

My reasons are because Ronaldo and modric played together at Madrid and Ronaldo was the best player in the champions league and the highest goalscorer in the champions league and also the highest goalscorer for Real Madrid itself.

Though Lukas modric was also fantastic but what gave modric the edge was his performance at the world cup,he had a great performance at the world cup and winning the golden ball gave him the edge.

So overall performance I will pick Ronaldo because of his goals,you can't win competitions without goals.

But anyway congratulations to Lukas modric.
