Roberto Mancini apologized to Manchester City's supporters after being knocked out of the Champions League and targeted success in the Europa League and Premier League.
Goals from David Silva and Yaya Toure gave City a 2-0 win over Bayern Munich in their final Group A match, but it was not enough as Napoli defeated Villarreal.
Premier League leaders City, who travel to Chelsea on Monday, will now take part in the second-tier Europa League in the new year, but manager Mancini remains focused.
"We go into the Europa league. It's another trophy and it's an important trophy for Manchester City," Mancini told Sky Sports HD2.
"It's a disappointment because we wanted to play in the Champions League.
"10 points is very difficult to go out.
"If you are in the final [of the Europa League] it will be very important because I've never won the Europa League.
"We are a good team. We played well, we're very sorry for our supporters and I'm sorry for our players.
"I think we need to improve as a team because we got a tough group [in the Champions League] this year.
"Congratulations to Napoli, they got one point more than us.
"Now we are the top of the Premier League and the season will be long, but we want to improve on last year in the Premier League."
