That rationale is very similar to where I'm coming from, mate... I clearly stated that, on his best day, DL is the better footballer. But those days were few and far between, and I always expected a howler out of him. I don't with NP. I expect limited but sensible and usually sound defending from him. Hence, as a 4th choice, I'm going with him.
I think thats slightly unfair on Lovren to suggest his good games were few and far between. We bought him because he was one of the best defenders in the league at the time. Hes a popular punching bag because so obviously a massive that who loves himself and has no self awareness, but Phillips is not at his level, or even close to it he will probably be Championship football next season.
