Sacchi said the match was a "triumph for football" and praised Inter's ability to score a "deadly one-two" and then adjust their strategy to defend against Barcelona's comeback.
He noted that Inter's second-half performance was more aggressive and attacking, with the team showing a "great spirit of sacrifice" in containing Barcelona's attacks.
Sacchi also commended Inter's coach, Simone Inzaghi, for his tactics and ability to put Barcelona in difficulty.
Looking ahead to the second leg at San Siro, Sacchi believes Inter have a good chance of winning. He emphasized the need for the team to recover physically and mentally, and to get some key players back to full fitness.
Sacchi thinks Inter have the ability to cause problems for Barcelona in the return match and send the Spanish team into crisis.
