Manchester City boss Manuel Pellegrini was delighted after his side's impressive 3-1 win away at Dynamo Kiev.
The Chilean started last weekend's game at Chelsea with five teenage full debutants and the decision was justified as the Citizens registered a very important result at the Valeriy Lobanovskyi Dynamo Stadium.
They will host the Ukrainians at home on March 15.
"I'm very happy," Pellegrini said.
"It's a very good result. Of course, it's not finished - we have to play the second leg at home - but I think playing away and having a two-goal difference is a good result.
"We played very well - we created a lot of chances - and we pressed very well.
"Dynamo are a team who like to make a short build up. We recovered the ball well most of the time and because in the first half we pressed high, we created at least three more chances.
"Maybe at 2-1 there were some moments of doubt but finally, we recovered the ball and scored the third goal.
"In football, you never think all is finished but the third goal gives us more confidence for the second leg.
"From tomorrow, we will think about the Capital One Cup final," he added. "It is very important to win a trophy.
"Then, when we finish the Capital One Cup, we must concentrate on the league.
"We have to fight for another 36 points."
