Modric – who was crowned UEFA's 2017-18 Player of the Year on Thursday – has been at the centre of speculation regarding a move to Serie A side Inter.
"I am in the best club of the world," Modric told reporters after beating former team-mate Cristiano Ronaldo to the award in Monaco. "I want to be here.
"I am not happy, I am super happy being here, very quiet and I just like to keep working doing well things like last six years."
Modric – who also won the Golden Ball at the World Cup in Russia after leading Croatia to the final – added: "As I already said, I am really happy to be here.
"I have been working to achieve as high as possible, so thanks to god I am here. This is the best year of my career collectively and individually, so I am really enjoying, we have to keep working."
