Since WW2, Coventry City have hosted 12 FA Cup replays and lost only three, and two of those after extra time. The only side to beat Coventry in ninety minutes was Bristol City in 2007 – a result which precipitated Micky Adams' departure the next day. Portsmouth (2010) and Huddersfield (1955) both needed extra time to win replays in Coventry, and the latter were also a top flight team back in '55.
The record is pretty impressive and one only hopes the omens are good for the replay on Tuesday. The full list of those post-war home replays is as follows:
1952 Leicester C won 4-1
1955 Huddersfield lost 1-2*
1962 Millwall won 2-1
1963 Portsmouth drew 2-2*
1966 Crewe won 4-1
1974 Sheffield Wed won 3-1
1981 Leeds won 1-0
1984 Wolves (2nd replay) won 3-0
2003 Cardiff City won 3-0
2007 Bristol City (h) lost 0-2
2009 Blackburn (h) won 1-0
2010 Portsmouth (h) lost 1-2*
