4 Clubs who can stop Barcelona from winning the Champions League this season

#2 Manchester City

Guardiola has in-depth knowledge of Barcelona

The earliest Barcelona and Manchester City can meet in this season's Champions League in the final and if it does happen, what a fixture that would be, as it would signify a clash of similar styles, reuniting student with teacher as the master tactician himself Pep Guardiola attempts to stop unarguably his best prodigy.

The Manchester City manager was the coach of Barcelona for four absolutely blissful years and under his management, the club enjoyed the most successful period of its history, conquering all before them to win 14 out of 18 trophies available, with the pinnacle being the total sextuple sweep in 2009, while he also spent 17 years of his playing career with the club.

The 48-year-old has expectedly taken his methods with him to England at Manchester City and their fortunes have been transformed since he took charge, with the club blitzing all before them to win the Premier League title last season, while they remain on course to become the first English team to win a quadruple.

Given the size of their pockets, it comes as no surprise that City has the largest squad depth in all of Europe and it says a lot that the club has been able to cope without the services of world class performers like Sergio Aguero, Kevin de Bruyne, David Silva but to name a few for long periods without batting an eyelid.

With Guardiola's in-depth knowledge of Barcelona's players and the quality of City's squad, the Cityzens have more than enough to deny Barcelona although they would have their hands full eliminating Tottenham first.
