If there's anyone who knows Sigma Olomouc well, Sevilla's next opponent, it's Vaclik, a Czech international himself and who has played for Vitkovice, Viktoria Zizkov and Sparta Prague from 2007-2014. This is why he attended an interview with Sevilla's Official Media to analyse our rival on Thursday at 19:00 CET: 'I've only got positive things in my mind about Sigma, they've improved a lot in the last two years. Two years ago they were playing in the second division and in the first season they got promoted in first place with a lot of young players and players from the academy, so they have a big heart and a connection with the city and the region. They play good football. I know the manager because he was the assistant manager at Sparta in my last season when we won the double, so I've only got positive things in my head. We're going to face a really difficult opponent, they're very aggressive and they play modern football. They'll press us, they're going to play, they're not a team who only wants to destroy, they want to create chances and play football. I'm looking forward to playing these games.
