VDW is only 8.5 mill do not spend 1.mill more
As Liverpool I've signed:
DR - Gregory van der Wiel from Ajax (£10M) He's one of my best players and I highly recommend him. He's still quite young but unfortunately he's quite expensive.
DR - Diego Renan from Cruzeiro (£7.75M) He's young and can also be played as a left back.
DL - Lucas Digne from Lille (£3.7M) Young, cheap and a good player.
Hope this helps.
