After a pulsating 2-2 draw at Camp Nou last week, both teams will be looking to book their place in the next round in what promises to be an enthralling encounter.Despite falling behind early on in the first leg, the Red Devils, powered by the unstoppable Marcus Rashford, fought back and leveled the scores before a Jules Kounde own goal gave them the lead. But the Blaugrana showed their quality and managed to salvage a draw with a late goal from Raphinha.Under the tutelage of the legendary Xavi, Barcelona have been in fine form this season and currently sit eight points clear at the top of La Liga. They extended their unbeaten run to 18 matches with a comfortable 2-0 win over Cadiz last weekend.The Catalan giants have also won their last 11 away games in all competitions. However, they have tasted defeat at the hands of Bayern Munich and Inter Milan in the Champions League this season.Manchester United, on the other hand, will be looking to end their recent hoodoo against Barcelona, having failed to beat them in their last five meetings. But with both teams in red-hot form and determined to progress in the competition, it promises to be an impressive showing.
