Sevilla, having picked up 11 points from their opening five games, looked set to continue their impressive start to the campaign last Saturday as they built a 2-0 lead against La Liga leaders Barca.
However, the match was to end in bitter disappointment for the Andalusian side as Barca fought back and, after Sevilla had been reduced to 10 men, two goals right at the end enabled Tito Vilanova's men to snatch a 3-2 victory and continue their 100% start to the season.
Now Sevilla will be hoping to get back on track against Celta tomorrow [Friday] and move level on points with third-placed Malaga, who are away to second-placed Atletico Madrid on Sunday.
Michel said today: "Celta are a Primera Division team and we cannot be thinking about the past and what has happened. We need to think about our qualities and the good moment we're in.
"Celta are a team at a good level. They are one of the few teams who start play from the back and up front they have reliable strikers, and in Iago Aspas they have a player who is going to be very difficult for them to keep hold of.
"Therefore we need to be careful. Our adrenaline cannot come from our opponents, but from ourselves."
Aspas scored 23 times in the Segunda Division last season as Celta won promotion back to the top flight and he has netted twice already this term, including in last weekend's 2-1 loss to Granada.
That defeat left the Galician outfit in 14th spot in the table on six points, but with all those points coming from home games, Celta will be optimistic about getting a good result tomorrow [Friday].
Defender Gustavo Cabral said: "We are making ourselves strong at home, and this is essential. We need to continue along this line."
Regarding Sevilla, the Argentinian said: "Despite losing, they had a great game against Barcelona and I'm sure they will be coming here looking to make up for that game."
