"I think what happened to Russia must ring alarm bells for all the teams who have to win their last game," said Torres in a Press conference.
"Even with six points, you can still go out. We must be aware of that, especially when facing a difficult opponent like Croatia.

"Don't forget Russia conceded a goal and were eliminated..."
