Chelsea boss Carlo Ancelotti had no complaints after his side were beaten by Inter Milan at Stamford Bridge on Tuesday night.
The Italian champions deservedly booked their place in the quarter-finals of the UEFA Champions League thanks to a 79th-minute winner from Samuel Eto'o.
Inter were 2-1 up after the first leg at the San Siro and Ancelotti - formerly coach of Inter's rivals AC Milan - believed Jose Mourinho's side had deserved to win.
He said: "They played a very good game. We were not able to play how we wanted. Inter deserved to win. We are very sorry but this is the reality.
"We were never in control. Inter put us under a lot of pressure and were dangerous on the break. There were only short periods when we could control it."
Ancelotti refused to criticise German referee Wolfgang Stark despite having two penalty claims turned down against Drogba.
But he admitted that he would come under increased pressure considering the Champions League was Abramovich's priority this season.
Chelsea are still in second place in the Premier League behind Manchester United and in the semi-finals of the FA Cup.
Ancelotti said: "We have to be strong and have control of our emotions. Maybe the defeat could be very good motivation for the next games.
"My regret is that we did not play as well as in the first leg. I've worked a long time in this environment and it is normal that the manager comes under more pressure if he loses a few matches."
