Getting the Champions League title is not as easy as other domestic leagues, the Champions League is a collection of great teams all over Europe so it will not be easy for Barcelona to achieve that dream even though they have brought their team to a great performance.
The Champions League has a different sensation and the mentality of coaches and players is still influential if they do not have deep experience in the UCL, I believe Barcelona this time will be better to go to UCL even though the previous season could only stop at the group stage.
Every coach's dream is to win UCL. For this, the economic strength of the team is also very important. Not every team, only one team can achieve this. Last year, Manchester City looked like an excellent team and they won the UCL. It's been a great season for Pep and we can see similar things happen this year. They will have tough opponents and UCL will again be the most watched tournament.
But it's not an easy task for a coach. Yes, there is only one team that has won but there is one team that has won consecutively; Real Madrid.
Although Manchester City is able to win the UCL but it is not impossible to win again even though it is still said to be a tough team, not that I don't believe Manchester City but that dream is many other clubs he dreams of.
With the club being able to win the UCL, financially and also the market price of players increases.
In as much as Manchester City would like to dominate the UEFA Champions League competition after winning the European title last season for the first time in the history of the club, there's a minimal chances of establishing such dominance in Europe especially now that many other clubs are wary of Manchester City.
Pep Guardiola is known for his relentlessness to achieve records that seems very to difficult to get but I think dominating the UEFA Champions League is something that may never happen
