Welcome to Liverpool Kolo!
It's an odd transfer, it's very easy to stand back and think "He's on a free, has been playing well for City, their fans are unhappy about losing him, he's apparently taken a wage cut, so what's the catch?", however I think we've acted quickly and taken advantage of a club that is currently not being ran very well, much like how we took advantage of Inter and Chelsea in January.
If we can get another centre half like Kyriakos Papadopoulos, then we'll have three very good centre backs able to challenge for the two positions and then maybe Coates or another signing as back-up, I think we'll be in a very strong position for dealing with fatigue and fixtures.
