I still think we need to sign players we were crying out for last summer: a right back, a back up keeper worthy of the name and a solid, experienced centre half.
However, the calibre of those players or any other players JC decides we require is likely to be dictated by where and how we finish the season. If we qualify for Europe, we may well sign an extra player or two or spend more on wages. As far as actually finishing the season, I think third is gone. As SOTR says, if it was just one of United or Hearts I'd say we could make it but hoping for both to chuck it away and for us to go on a run is very unlikely at the best of times, but at this moment in time it's even more unlikely considering how our results are going and how wasteful we are in front of goal and how spasticated we are at the back.
We've got to keep on keeping on, obviously, but I think the best we can hope for is fourth.
