FA Cup holders Arsenal were taken to extra time before a horrendous error by Reading goalkeeper Adam Federici brought the Championship side's dream to an end in a 2-1 semi-final defeat on Saturday.

Arsenal's Alexis Sanchez snatched his second goal at the end of the first extra period to subdue the plucky second-tier strugglers, but his tame goalbound shot barely trickled over the line after being spilled by the devastated Federici.
