MADRID, Sept. 19 (Xinhua) -- Cristiano Ronaldo's return to Spain in his Champions League debut with Juventus ended after just 30 minutes of their match away to Valencia on Wednesday when he was shown a direct red card by referee Felix Brych after a tussle with Valencia defender Jeison Murillo.

Ronaldo walked off the pitch crying with frustration and clearly saying "I haven't done anything."

It is the 11th time Ronaldo has been sent off in his career: 4 times with Manchester United, 6 with Real Madrid and now once for Juventus.
