Federici gifts Gunners winner

The Royals keeper, who had made some fine saves earlier in the match, allowed Alexis Sanchez's low shot to squirm between his legs and over the line on 115 minutes, which was enough to see the Gunners return to Wembley on May 30 to try to defend the trophy.

Sanchez had swept the Gunners into the lead on 39 minutes.

However, Reading were level when Garath McCleary's volley was deflected past goalkeeper Wojciech Szczesny, who could only palm the ball back over the line.

Arsenal twice hit the woodwork through a header from defender Gabriel and a close-range shot by Aaron Ramsey, but could not find a winner in normal time.
