I'm pretty neutral about Manchester City's chances of winning the Champions League title. It is unreasonable at this time to expect Manchester City to miss out on their first title although in most cases Pep Guardiola has not been able to prove that with any other team apart from only Barcelona. Pep Guardiola has to prove it that he can, and this season is the time to prove it.
Guardiola's main problem is actually about how he can spoil Inter's strategy which might try to defend well. It's not uncommon for Inter to play their tight defensive side when Guardiola and his team tend to dominate the game, it will be exciting to watch.
This is isn't Pep Gardiola first time to get here with Manchester City , went to finals with Chelsea but unfortunately he lost in that final. I do believe some lessons has been learnt , some improvement and more experience gained by this City's team right now to compared with the squad then that played with Chelsea. Inter would find it difficult to face Manchester City style of play , which basically they always play to dominate the entire midfield and which will result to mounting pressure on Inter's defense.
