Of course he'd benefit going out on loan, obviously with a team meeting qualified opposition and preferably playing in a way comparable to us. The key is getting as much competitive playing time as possible, as nothing can quite match that. Jacob being talented is just a plus, as it would mean bigger chance that he gets playing time even in a rather good team.
Some progressive team in the upper half of the championship would be ideal, half a year there after we strengthen in the January window sounds good to me. He will come back in the summer, stronger, hungrier and more mature, ready to make some serious impact.
