Milner told BBC that the boss waited to sign his contract before the boss signed his own, and that made him feel important.
I'm not questioning milners abilities here, he is a tank and proper fit player but I think boss wants him not just for what he does on the pitch but off it too.
One of klopps strengths are keeping the squad happy and playing for each other, seems to me that milner is vital part of it that puzzle.
I personally would want him at Liverpool staff after his playing career is over, let him take his coaching badges. See how klopp works and nurtare him to take over klopp when that day comes.
I love stevie, but let's not all gamble on one horse. Let stevie do his thing at rangers and milner under klopp. See who is more capable to manage when that day comes.
