Sevilla are closing in on a place in the Europa League semi-finals as they lead 1-0 in the quarter-final second leg against Zenit St Petersburg.
Zenit need to score at least two goals in the second half, after Sevilla won the first leg 2-1.
Sevilla took the lead early after Neto took down Vitolo inside the penalty area, and Carlos Bacca directed the ball into the top corner from 12 yards.
Oleg Shatov saw his shot blocked by Daniel Carrico in the 10th minute, before Hulk shot wide of the target from outside of the penalty area.
Seven minutes later, Danny drove into the Sevilla area but his shot was stopped by Beto's diving save.
Aleix Vidal then had the ball in the net for Sevilla in the 23rd minute, but his goal was disallowed after Vitolo had handled during the build-up.
Vidal then looked to have breached the Zenit defence in the 31st minute but Nicolas Lombaerts was able to make a last-ditch tackle.
Bacca had a great chance to double Sevilla's lead just before half time when he rounded Juri Lodygin, but his shot was blocked by Lombaerts.
Danny's free kick caused problems for the Sevilla defence in stoppage time, and the Portuguese struck the post a minute later.
