4. Daniel Agger
Next up is yet another defensive bargain signed by former Liverpool boss Rafa Benitez. Daniel Agger may have suffered from a multitude of injury problems since moving to Liverpool in 2006, but the Dane has still made almost 200 appearances and established himself as one of the leagues finest centre backs with a great eye for a pass and a deadly shot. He has been a fans favourite ever since scoring a 35 yard screamer against West Ham to mark his first goal for the club and until his partners recent downturn in form was part of one of the leagues best centre back pairings alongside Martin Skrtel. The 28-year-old was apparently subject to a
£20 million bid from Manchester City in the summer, a figure which only highlights how highly rated the defender has become, and how good value he was at just
£5.8 million.
