Can Chelsea v Middlesbrough Carabao Cup semi-final go to extra-time and penalties?

The Carabao Cup has reached it's business end with both semi-final second legs taking place this week with a place in the Wembley final the reward for the winners.

On Tuesday evening Chelsea host Championship side Middlesbrough at Stamford Bridge. The Teesiders hold a 1-0 advantage from the first leg after Hayden Hackney scored the only goal in the first leg at the Riverside Stadium.

Fulham will need to produce at fightback against Liverpool on Wednesday if they are to reach their first Wembley cup final since 1975. Marco Silva's team took the lead through Willian in the first leg at Anfield but a second-half fightback has given the Reds a 2-1 advantage heading to Craven Cottage after goals from Curtis Jones and Cody Gakpo turned the tie on its head.

With just one goal separating the sides in both fixtures there could be a tight finish in both contests, but no matter the outcome, but ties need to bee decided on the night.

This year's Carabao Cup has seen all ties settled in one game with no replays. There has also been no extra-time. Any matches that were drawn after 90 minutes went straight to a penalty shoot-out to decide a winner.

That all changes at the semi-final stage, however. The final four of the competition is the only round of this season's Carabao Cup played over two legs, home and away. In the event of the aggregate scores being level in either tie after 90 minutes of the second leg, the match will go into extra time where two periods of 15 minutes will be played.
