South Africa s Aaron Mokoena scored in the final minute of extra-time as crisis club Portsmouth came from behind to beat Coventry City 2-1 in an FA Cup third round replay on Tuesday.
Victory gave Portsmouth, bottom of the Premier League and beset by financial problems, a fourth round tie at home to top-flight rivals Sunderland.
Both of Pompey s goals were heartbreaking for second-tier Coventry, coming in the last minute of normal time and in time added on at the end of the second half of extra-time.
The 2008 FA Cup winners were behind for most of the match after Coventry striker Leon Best fired the home side, who play in the second division Championship, into a 22nd minute lead.
And it seemed cash-strapped Portsmouth, whose officials met earlier Tuesday with Premier League chiefs in a bid to lift the club s transfer embargo, were about to exit the FA Cup until Coventry s Stephen Wright headed into his own net shortly before the end of normal time at the Ricoh Arena.
The tie was heading for a penalty shoot-out until defender Mokoena headed in the winner with virtually the last act of the game.
