Daniel Alves and Javi Navarro expect a tough test in the second leg of Sevilla's Uefa Cup quarter-final against Tottenham.
Robbie Keane scored a vital away goal for Spurs after just 68 seconds but Sevilla recovered well and will take a 2-1 lead to White Hart Lane for the return leg next Thursday.
Alves feels his side have a slight advantage but is anticipating a tight game on the Premiership side's home turf.
"The passage through to the semi-finals currently stands at 55 per cent for us and 45 per cent for them, since we are winning," said the Brazilian full-back.
"However, we need to remember that we have 90 minutes left and anything can happen. It will be a difficult game and we have to show what we are capable of.
"We are aware of the difficulties we are going to have, since we are up against a very strong opponent, although we will go there with a small advantage."
Navarro admits he was impressed by Tottenham's quality, but is still confident Sevilla will advance to the semi-finals.
The centre-back urged: "We have faith that we will get through this round and will fight until the end to obtain it.
"Tottenham are a good team, with very strong players who, at any moment, could make the game complicated.
"They have players with much quality and strength who can cause you damage."
