I would be shocked if the Albion arent looking a bit deeper in Burkes mental state.
I dont recall seeing a player look so unhappy and disinterested in football, he looks as though he would rather be anywhere else than on a football pitch, his body language is poor.
I dont know whether the pressure of two big moves have got to him, i know there was that report about him from the Scotland under 21 squad last year which said he had become withdrawn and isolated, he just doesnt look happy.
We have probably all had jobs we struggle with and at times dont want to be there, it looks like maybe there is element of that, problem is he is having to do his job in front of thousands of people. Of course he gets paid money we can only dream of and he has the best job in the world but the brain is a funny thing and doesnt decide who can struggle and who cant based on their money or job.
I may be completely wrong, i dont think for all the above he is a natural footballer, he doesnt seem to have a football brain but as many others have shown you can have a good career playing to your strenghs, he is big quick and strong, you have to make full use of that and not try and teach him to be something he isnt but before any of that i would be looking into his mentality and state of mind.
