Both teams has quite a record in the Champions league although Real Madrid have dropped drastically in terms of form and Manchester City on the other hand are showing huge improvement this season. I think Real Madrid will be facing a tough test going head to head against this formidable Manchester City team.
It's ancelotti's ersponsibility to bring back the best performance of real madrid again. Real madrid has been suffering the bad result in the previous matches on la liga. I do know if people may feel doubt caused by real madrid got some bad results in the local league.
Ancelotti will have done so many evaluations to the performance from real madrid in the previous games. It's likely that if madrid gonna try to rotate some players too against manchester city.
Its defenders have become the main concern as madrid conceded so many goals during the last games against girona and sociedad. It's unacceptable result to see madrid has very weak defensive line this time.
A lots of works must be done by ancelotti as a response to fix the problem that has been coming to the real madrid.
Madrid needs to focus first against osassuna caused by it's also a final match in copa del rey. Madrid may use it as a way to boost its mentality before it will face city.
