It has been for a few years now Greg and successive managers have done precious little about it. But yes, its now of immediate and pressing concern. If Pearo goes, which looks very likely, we'll need about 3 central midfielders I think. Pre season starts tomorrow and that doesn't give us much time to sign replacements and get them up and running. Mark McGhee has always liked a powerful midfield and he now has the opportunity to create his own, albeit hastily. That said, he will have known for some time Jack Leitch would leave, Gomis would return to Hearts, Keith Lasley is probably in his last season and that Pearo might leave.
Certainly the rebuilding job is much more extensive than I had anticipated.
