When Real Madrid lost several previous matches because many of its players were injured so that Real Madrid's performance could not be maximized, Benzema was the key to victory for Real Madrid; if Benzema did not fully contribute, then Real Madrid would find it difficult to win in every match. As for Chelsea, even though they have a new coach, they still cannot achieve what they want this season. Chelsea can only hope that next season they can get back up.
Real Madrid has had a good season but their quality cannot be compared to last season. Last season the team was at the top of their game and Benzema was scoring goals and had fewer injuries. This season Vini Jnr is too young to shoulder the attack of Madrid due to the constant absence of the world's best player. Concerning the Champions league both Chelsea and Madrid lost their last matches so it will be not wrong to state that although Chelsea's performance has not been encouraging, they still have a chance of picking at least a draw in Santiago Bernabéu. It might be the greatest surprise of the tournament for Chelsea to qualify for the semifinals, but in football, you don't say it is not possible because all things are possible.
