Chelsea are left biting their fingers after former Chelsea man Kai Havert rounded goalkeeper Sanchez up before putting the ball into the net yesterday and booked a place for the Gonners in the final in Wemble.
The two teams ended the first leg 2-3 with Arsenal taking a goal advantage to the Emirate stadium.
And Chelsea put in a spirited display with a determination to turnaround the first leg deficit but it was not to be as they were up against Arsenal who has the best defensive record in the league.
In the end they came off with a defeat giving the Gonners a well deserved Wembey final ticket.
Chelsea coach Liam Rosenior got it all wrong from the beginning when he started five men in the defense which made Arsenal very comfortable because they had a goal advantage. It was okay for them to just sit back and allow Chelsea to attack
Arsenal will play against either Man. City or Newcastle in the finals.
