I'm not against either Barkley or Carroll tbh.
Fit and on form Barkley can be a powerhouse who would certainly give us some directness amid all the fancy stuff. Andy Carroll would have been very useful of late where I feel we've lacked the ability to 'rough them up' a bit. Both players would offer us an alternative to what we have and add a little more depth to us.
Great news regarding Tibo but not so great news if Luiz wants out.
I take Barkley and Tibo to be the most likely to happen.
