Fine goals from Mexican teenager Carlos Vela and Eduardo either side of half-time, coupled with Emmanuel Eboue's late strike, set the Gunners up for a home tie against Hull in a fortnight's time.

The victory also extended Arsenal's unbeaten run to 17 games in all competitions and proved just the right tonic ahead of next week's crucial Champions League trip to Roma.

A remarkable turnaround sent Everton back to Wembley for the first time since 1995.

Middlesbrough had stifled the Toffees in a poor first-half and were leading deservedly at the break through David Wheater's header a minute from half-time.

But Everton boss David Moyes made an inspired substitution at the break, sending on Louis Saha for raw youngster Jack Rodwell.

Everton stormed back with two goals in six minutes at the beginning of the second period. Marouane Fellaini headed Everton level before Saha soared in the six-yard box to head the winner to set up a semi-final trip to Wembley.

In the semis Everton will face Manchester United while Chelsea meet the winner of the last eight tie between Arsenal and Hull.
