Manchester City booked a return to Wembley despite defeat to Manchester United in another derby marred by crowd problems.

Nemanja Matic scored but was later sent off as United claimed a 1-0 win at the Etihad Stadium that was not enough to prevent City prevailing 3-2 on aggregate in their Carabao Cup semi-final.

The result ensured City, bidding to win the competition for a third successive year and a fifth time in seven seasons, would face Aston Villa in the final on 1 March.

But headlines were also made in the stands with tensions running high between both sets of supporters.

Missiles were thrown and some City fans were filmed making aeroplane gestures in reference to the Munich air disaster, the 62nd anniversary of which is on 6 February.

This came after the Premier League meeting between the two sides at the same venue in December was overshadowed by a City supporter making a racist gesture towards United players.

It also happened just a day after the home of United's executive vice-chairman Ed Woodward, who attended the game, was attacked in a sinister escalation of the vitriol aimed at him in recent weeks.

City manager Pep Guardiola said: "When you talk about what happened, I didn't know it. If it would happen, that is not nice. Absolutely not.

"I don't like what happened with Ed Woodward at home because this is football."

Opposite number Ole Gunnar Solskjaer said: "I've just got to stand behind Pep there.

"Yes, we want rivalry but let's keep it at a sane level and let's make sure we eradicate that now."
