Real Madrid captain Sergio Ramos fired a warning to the rest of Europe after their Champions League win over PSG.

Cristiano Ronaldo struck twice, with Marcelo also scoring as Real won the first-leg of their round 16 clash 3-1. Adrien Rabiot netted for PSG.

At the final whistle, Ramos declared: "There are days left to remember, and what better way than to do it with this personality, it's an important victory for the return (leg), we have to keep it that way, so serious and wanting to defend the Champions League.

"Any mistake can leave you out and in Paris we have to maintain the maximum concentration, we have been more effective than before ... Real Madrid can never be considered dead.

"We have taken an important step, but it is open, we have to keep working."
