Zola has reflected on the season so far and explained why he feels there is still much to play for between now and May.
"This season perhaps hasn't been quite as good as last season but the team is still doing well," Zola told chelseafc.com. "Chelsea did very well in the first leg against Barcelona and will hope to get through [to the next round of the Champions League] in the second leg. They can still push on in the Premier League too and have a strong finish.
"Compared to last season, yes, of course it's not as good, because Chelsea dominated the league so much. The Premier League is such a difficult competition, so it is uncommon to see a team dominate for two or three years in a row.
"It used to sometimes happen back in the day, with teams like Chelsea, Manchester United and Arsenal, but now the competition is so high, it doesn't really happen anymore. But there is still plenty to play for. The Champions League is still open for us and there is still plenty available for us to have a good season.
"Of course we know it will be difficult in the Camp Nou, but we have to go there and give it everything. We need the fans to get behind the players and show their support. Hopefully there will be many fans there and hopefully they will be coming back happy with a win."
