United win but City reach final on aggregate
Pep Guardiola called on Manchester City to learn the lessons of a 1-0 home defeat to Manchester United on Wednesday despite progressing to a third successive League Cup final 3-2 on aggregate.
The holders enjoyed the vast majority of the chances but could not find a way past the inspired David de Gea and went behind to United's first attempt on goal 10 minutes before half-time when Nemanja Matic fired home.
United's hopes of completing a miraculous comeback were extinguished when Matic was then sent-off 15 minutes from time and City held on to face Aston Villa at Wembley on March 1.
"In 180 minutes we were better than United," said Guardiola. "We created chances to score a lot of goals and didn't convert. We need to learn to be more clinical."
City started like they did in racing into a 3-0 lead within 38 minutes of the first leg at Old Trafford as they swarmed all over the visitors, who had De Gea to thank for keeping them in the tie.
"I can't really comprehend how we lost this game," said City midfielder Kevin de Bruyne. "I think we got sloppy.
"For me Manchester United didn't have one chance today."
Sergio Aguero was first to threaten with a diving header that the Spaniard parried to safety before using his legs to repel Riyad Mahrez's effort.
Bernardo Silva flashed a shot across goal before more De Gea acrobatics denied Aguero again at his near post.
