Group F leaders have the chance to take a big step towards the knockout stages against Slavia Prague
Barcelona have so far navigated a tough Champions League group to occupy the top spot with seven points after three games, three clear of second-placed Inter Milan.
But the Spanish champions have yet to produce a vintage performance, drawing at Borussia Dortmund and claiming wins over Inter Milan and Slavia Prague by one-goal margins.
Barca have arguably their best chance to deliver a more emphatic scoreline on Tuesday evening when they host Group F's bottom side, Slavia Prague, at Camp Nou.
The day before the game, Barcelona players including Lionel Messi, Ansu Fati and Antoine Griezmann took part in a training session at the club's Joan Gamper Sports City as the squad completed final preparations.
