I probably know a lot of things that you don't, how's your astro-physics.
However I know nothing of the workings of the transfer committee although personally I don't rate Walker. Its just my opinion but I am entitled to it.
Not rating Walker is different from saying we can kiss goodbye to the CL with him.
As it happens, the guy who wants Walker in his side knows a thing or two about squad building and winning the Champion's League, so I wouldn't worry too much.
