"Of course [they are contenders]. I'm not surprised by how well they're doing. They've been looking extremely strong and organised since last year, and they have a top coach. It's a very strong team and will be going for the title this year. Atlético is a very strong contender, but I'm convinced Real Madrid will win it in the end," said Ronaldo.
