Real Madrid defender Roberto Carlos could face a Champions League ban following a clash with Bayern Munich’s Martin Demichelis on Wednesday.

The Brazilian appeared to strike Demichelis in the face after a tackle between the two. Although the referee did not see the incident, tellevision replays hav e been brought to the attention of UEFA who have decided that the former Internazionale full back has a case to answer.

“We’ve opened a disciplinary case against him and a decision will be announced by about 5pm on Monday (March 1),” stated a Uefa spokeswoman.

“There are many possible sanctions available. The most likely would be a suspension for one or several matches.”
