I sort of get where you are coming from. If we did sign him, he'd blatantly get time in our team and I reckon would do OK.
From a purely footballing point of view, a 6 month deal makes sense for him, he'll get decent PL minutes with a view to a tournament swansong this summer, it sort of makes...
Sorry, without reading through all of this is there any reason to think this might happen or is it wild speculation?
My initial irrational thought is, I don't want it to happen, in the same way as I didn't want Murray back. Likely he'd do well for us
