Real Madrid bus attacked
According to Spanish daily El País, the police formed a barrier to prevent the Atlético fans advancing. Again according to El País, the local supporters had attacked a Real Madrid supporters' bus with bottles and stones, causing at least one injury.
The injured Real fan spoke to Spanish radio station Cadena SER, explaining: "I've been given three stitches and I was told that if I wasn't feeling dizzy I was OK to see the game but to go to hospital afterwards, because the knock I took was to the head.
"When we were arriving at where all the coaches were, they started to throw bottles, there were people spitting at the windows and we were a little bit afraid. There was a father with a boy and a girl, and when they started to throw bottles I protected them; they hit me, but they didn't hit the kids."
