The Barca manager praised his side for securing an injury-time win over the hosts, and he hailed the play of newcomer Alex Song.
Piotr Trochowski and Alvaro Negredo put the home side ahead before a double from Cesc Fabregas and a stoppage-time winner from David Villa completed the turnaround. Vilanova insisted that the victory was deserved, and opined that the spirit shown by Barca to bounce back from the jaws of adversity is testament to their winning mentality.
"A draw would not have been the fairest result," Vilanova told club's official website. "[We] created enough chances to win the game. It would've been better to not suffer, but it's important to have the ability to sacrifice yourself in order to continue competing. That is what my team did throughout the match. A team that fights back proves that they want to keep on winning."
Vilanova also spoke about Alex Song's performance on the night, holding praise for the former Arsenal man as he continues his transition to his new side.
"We’ve asked a lot of him [Song] lately, because he was forced to play in a three-man defense," Vilanova said. "I think he had a great game."
