#3 Alvaro Morata vs Clement Lenglet
Alvaro Morata has made a brilliant start to his Juventus career and he will be looking to continue his good form when he comes up against the Barcelona defence led by Clement Lenglet on Tuesday night.
The former Real Madrid and Atletico Madrid striker has been in lethal form and is currently the joint top scorer in the Champions League with 6 goals in 5 appearances.
Clement Lenglet, on the other hand, has not been at his best. The French center-back really struggled against Cadiz and will have to put in a much improved performance to keep the Spaniard in check.
#2 Antoine Griezmann vs Matthijs de Ligt
Much has been made about Antoine Griezmann's impact and form in a Barcelona jersey, but in the last few matches, the talented Frenchman has slowly started to show his class.
The Barcelona forward's relentless energy and intelligent movement will keep the Juventus' backline on its toes and young Matthijs de Ligt will have his hands full to keep the temperamental Frenchman in check.
Matthijs de Ligt himself has slowly started to find his way back to the Juventus team after a long injury layoff and will be itching to make a good impression at Camp Nou under his former national coach, Ronald Koeman.
Skilled on the ball and brilliant in the air, De Ligt will be hoping to strangle Barcelona's attacking play and shackle Antoine Griezmann to give Juventus the edge on Tuesday night.
#1 Cristiano Ronaldo vs Lionel Messi
Was there any doubt as to which would be the #1 battle on this list? The matchup which all football fans have been waiting for with bated breath, Cristiano Ronaldo vs Lionel Messi promises to be the main talking point of this blockbuster clash.
The Portuguese superstar has started the season in fine form for Juventus and will be eager to continue this against his great rival Lionel Messi. With 10 goals in just 9 appearances so far for Juventus, Cristiano Ronaldo is showing no signs of slowing down.
Lionel Messi, on the other hand, has not been at his brilliant best. The Barcelona maestro has failed to have his usual decisive impact on games. However, a clash against his eternal rival might just inspire him to create some magic at Camp Nou on Tuesday night.
Barcelona vs Juventus, Ronald Koeman vs Andrea Pirlo. Lionel Messi vs Cristiano Ronaldo. With both teams going hard for the win, it promises to be a blockbuster UEFA Champions League clash.
