Surely any manager coming in would have already...

tapped up a number of players to help ensure that he is a success in his new job.

if the manager chosen is a free agent i cant see why not but if he is all ready at a club he isnt guna approach players

I'm sure thats the case. I said a few days ago any potential manager would have sounded out targets (or their agents at least) we all know tapping up is rife in football! if you dont then, well, you need to be shot
