Champions League 2018-19: 5 players who would play a crucial role in helping Barcelona win 

#1 Lionel Messi

Villarreal CF v FC Barcelona - La Liga

This is the man upon whose shoulders all of Barcelona's hopes lie and given his other worthy talents, Messi has the requisite ability to carry such burden.

The Argentine international's performance level has been nothing short of phenomenal ever since he made his Barcelona debut in 2004, such that he has gone on to cement his legacy as the club's greatest.

Good luck to anyone else trying to match Messi's records in future, as they are so extraordinary that you needed to witness them to truly believe.

So far this season, the 31-year-old continues to set the standards and is already among the frontrunners for this year's Ballon d'Or.

However, Barcelona fans would be wary of their talisman's struggles in the one competition which they have their mind most set on.

Lionel Messi is without a Champions League quarterfinal goal since 2013 and it is no surprise that the Blaugrana have progressed past this stage just once since then.

This is an anomaly the number 10 would be seeking to correct and if he can successfully navigate his club past this stage, then there could be no stopping Barcelona.
