#3 Jordi Alba | Barcelona
Barcelona have been reliant on their old guard for much of their recent success. That includes the likes of Gerard Pique, Lionel Messi and Jordi Alba. Out of the trio, Alba has not received his fair share of the spotlight, and his contributions have gone under the radar.
He appeared in 35 league games last season, and has been irreplaceable at the left-back position. He has played just one game in the pre-season, though, so he will be raring to get back into action after a good outing with Spain at the Euros.
His contribution at both ends of the pitch makes him one of the key players for Barcelona. Although he won't be able to link up with Lionel Messi on the flanks anymore, he should be able to have a significant impact on the game on Sunday.
#2 Memphis Depay | Barcelona
Memphis Depay had a great outing with the Netherlands at Euro 2020, and has continued his good form with Barcelona as well, scoring on his debut, albeit in a friendly. He then scored again in the friendly against Stuttgart, and should be one of the first players on the team sheet for Ronald Koeman.
The former Manchester United winger scored 20 goals and had 12 assists to his name with Lyon in the 2020-21 campaign, so big things are expected from him at the Camp Nou.
Memphis Depay has the ability to play on either wing, and his decisiveness and maturity in the final third should help him create and score goals galore at will.
#1 Cristiano Ronaldo | Juventus
When Barcelona and Juventus clash on Sunday, all eyes will be on Cristiano Ronaldo. The player won the Golden Boot at Euro 2020, and will feature for the first time in the pre-season for the Bianconeri.
While a much-awaited duel against Lionel Messi won't materialise, Cristiano Ronaldo will look to make an impact in his first game of the pre-season. Even though this game is a friendly, Ronaldo could look to produce a strong performance against Barcelona.
He was the top scorer in the Serie A as well as the Euros. Ronaldo has been in great goalscoring form this year, something he'll look to continue in this game as well.
