I agree that mourinho has some temper issues but i think that the uefa are too lax on Referees and when they commit mistakes altering the outcome of games they do not take the appropriate measures, the chelsea vs barcelona game is a prime example so when managers or players get angry i think they have the right to do so to a certain degree.
This is very important issue and now UEFA needs to check this as well because they are suing technology for all things but still having serious issues which create controversies are never been good for the sack of game we have too many incidents like these which create serious trouble but still no one doing any proper debate about this all and have better use of technology as well which end this all, and we will have things without any big trouble.
José Mourinho and his player's reaction was surely temper issue but why they are having things like this which are not acceptable, hopefully in coming seasons we will be having improvement in referees and their way f managing matches.
