Thudd will win you games IMO, if you have someone to put the goals away (graham).
Afforded time, which you do get against mid-lower teams sometimes he can pull teams apart and dictate. Was a key member of the squad that came 4th the first time (I think) and had a good partnership with, I think, modric
Livermore isn't at our level for midfield, but then we have a LOT of midfielders. He's a good defensive md, can tackle, run all day, works hard and is decent in the air too. With a licence to go forward could also do damage, looked ok and got a goal or 2 (1 against barca in a preseason) when suck opportunity arrived.
You should be very happy, as should Cardiff with caulker, we are very generous, lol
