Victor Vazquez is looking to cause an upset in the Champions League play-offs on Tuesday night.
Vazquez and his Club Brugge teammates take on Manchester United at Old Trafford in the first leg of the final qualifying phase of Europe's premier club competition and the playmaker is looking to get one over his former Barcelona coach Louis van Gaal.
"We are the smaller team but they have to be worried. We are playing with confidence and we can be dangerous tomorrow," 28-year-old Spaniard Vazquez said.
He added: "It's always nice to hear about the big ones. I met him in Barcelona. I was young, maybe 11 or 12 years old but my impression was that he was a really hard coach with a lot of character and personality, just like he is now.
"I didn't meet him a lot of times but I think he is one of the biggest coaches in football, for sure."
