#3. Lionel Messi
To win the UEFA Champions League this season, Los Blaugrana will definitely need a source of great inspiration. And fortunately for the Catalans, they already have one in the Argentine superstar, Lionel Messi.
No matter what Barcelona's challenge is, Messi is the solution. The Argentine star inspired the LaLiga champions to claim their last four Champions League trophies and he will be there once again to lead them to another European glory this season.
Having opened his account with a brilliant brace against Alaves recently, the playmaker will be looking forward to taking his incredible form into the tournament this term.
On his day, he can take on opposing defenses all by himself, destroy them and inspire Barcelona to achieve important victories. With the attacker on the team, there is no doubt the Catalans have a big chance of winning the competition this time around.
