So just because people dont like O'Neill doesnt automatically mean they have a direct replacement in line.
If someone bangs on about a problem for long enough, I don't think it's unreasonable for others to expect some kind of solution to be suggested. Otherwise you're just part of a bigger problem.
Martin Jol for me. Much better manager than O'Neill on every single level. Better coach, better tactics, better in the transfer market, better knowledge of European football, and less likely to behave like a teenage girl with PMT.
Even if you're right about all that, there's still the tricky problem of him staying exactly where he is.
