According to the Daily Mirror

We tried to sign Andy O'Brien from Leeds Utd just before the emergency loan transfer window closed but it fell through when he rejected the loan + 18 month contract. Now I don't know what the rest of you think but having read the feelings of the Leeds fans about him as a player we might have been well out of this deal although Derek McInnis seems to be able to deal with anything that players can come up with, look at who he controlled and got the best out of at St Johnstone, what would you have thought about us signing the afore said Mr O'Brien either last week or during January, not that I think DM will make him another offer unless we have some serious injuries of major loss of form of our current squad.
Does anyone think A O'B would have been the commanding CB we were looking for or do you think that Lewin and Liam are starting to look the part now as I've said recently Liam has surprised me by how well he's playing atm and Lewin keeps improving.
