Barcelona technical director Jordi Cruyff believes they will defeat Inter Milan tonight.
Barca need victory to keep their chances alive of reaching the Champions League round of 16.
Cruyff joked on Cadena SER: “I'm optimistic by nature. So I'm sure we're going to win. If I said otherwise, my father would come and give me a smack."
Speaking of hs father, Johan Cruyff, Jordi continued: “The line between madness and genius is sometimes almost imperceptible. They saw my father at first as crazy, but in the end the results came and then he was already a genius.
"You just have to see that he is the only person who has two stadiums with his name (Ajax and Ciutat Esportiva del Barça)."
Jordi also recalled leaving Barca for Manchester United early in his playing career.
"I went bald due to the stress I experienced in Barcelona when I was 19 and 20 years old, so when I went to Manchester my life improved."
