Cristiano Ronaldo played down talk of crisis at Real Madrid after the European and Spanish champions were trounced 3-1 on their Wembley debut against Tottenham Hotspur on Wednesday.

The Portuguese scored his sixth goal in this year's Champions League and 111th overall but it was merely a consolation effort as his side were outplayed on their first ever appearance at the iconic stadium.

Defeat left Real second in Group H, three points behind Tottenham who will seal top spot if they win one of their last two games away to Borussia Dortmund or home to Apoel Nicosia.

Zinedine Zidane's side also trail Barcelona by eight points after 10 games in La Liga following a shock defeat by Girona at the weekend -- a result that means Real have suffered their worst domestic start for five years.

"You can't always be at your best -- there are good moments and bad moments," Ronaldo, who had never been on the losing side against Tottenham, including in 11 matches against the London club for Manchester United, told reporters.

"We're relaxed. What counts is what happens at the end (of the season), not what happens now. We need to stay calm.

"We're not in the best moment -- we have to accept that and keep working. We could lose three, four, five games and I still wouldn't think there's a crisis
