Sevilla midfielder Didier Zokora has spoken of his disappointment following his side's exit from the UEFA Champions League.
The 29-year-old Ivory Coast international crashed out of Europe's elite club competition on Tuesday with Sevilla, as CSKA Moscow progressed to the next round.
Sevilla were in a strong position going into the second leg in Spain, having grabbed an away goal in Russia following a 1-1 draw.
But they went down 2-1 at home to CSKA, meaning they go out at the first knockout round.
Zokora told skysports.com: "I am very disappointed with the result. We had done the difficult part in Moscow but we let ourselves and our fans down.
"It is painful, but it is football. We need to regroup and finish the league strongly.
"We will need to do well and qualify for the Champions League next season."
Sevilla are currently fourth in the Spanish Primera Division and have a good chance of qualifying for next season's Champions League.
Zokora will be playing in the first ever World Cup on African soil during the summer, and is keen to finish the campaign well in the run-in to the competition.
"Personally I need to finish the season strongly because of the World Cup," he added.
"It is a competition I might play in for the last time in my career like a lot of the Ivorian players.
"We are in a difficult group with Brazil and Portugal, so we will have to be our best to stand a chance."
Meanwhile, club president Jose Maria Del Nido insists that Manolo Jimenez will be the manager until the end of the season.
Supporters vented their frustration against the coach on Tuesday, but Del Nido says there will be no knee-jerk reaction after the defeat.
"It is clear that the people are divided on this subject but the directors have decided nothing about the coach," he said.
"Manolo Jimenez is our coach until the end of the season."
