Real Madrid coach Jose Mourinho and captain Iker Casillas are not on speaking terms. El Confidencial says the pair have not spoken beyond match requirements for the past month. The duo simply do not get on and president Florentino Perez is aware of the situation.

For the moment, Real are able to keep a lid on things thanks to the team's superb form.

However, should Real stumble in the Liga, or be dumped out of the Champions League, the feud could explode before the end of the season.
